"Vedic Mathematics" - Preface
A- A DESCRIPTIVE PREFATORY NOTE ON THE ASTOUNDING WONDERS OF ANCIENT
INDIAN VEDIC MATHEMATICS
1. In the course of our discourses on manifold and multifarious subjects
(spiritual, metaphysical, philosophical, psychic, psychological, ethical,
educational, scientific, mathematical, historical, political, economic,
social etc., etc., from time to time and from place to place during
the last five decades and more, we have been repeatedly pointing out
that the Vedas (the most ancient Indian scriptures, nay, the oldest
"Religious" scriptures of the whole world) claim to deal with all branches
of learning (spiritual and temporal) and to give the earnest seeker
after knowledge all the requisite instructions and guidance in full
detail and on scientifically- nay, mathematically- accurate lines in
them all and so on.
2. The very word "Veda" has this derivational meaning, i.e. the fountain-head
and illimitable store-house of all knowledge. This derivation, in effect,
means, connotes and implies that the Vedas should contain within themselves
all the knowledge needed by mankind relating not only to the so-called
'spiritual' (or other-worldly) matters but also to those usually described
as purely "secular", "temporal", or "worldly"; and also to the means
required by humanity as such for the achievement of all-round, complete
and perfect success in all conceivable directions and that there can
be no adjectival or restrictive epithet calculated (or tending) to limit
that knowledge down in any sphere, any direction or any respect whatsoever.
3. In other words, it connotes and implies that our ancient Indian Vedic
lore should be all-round complete and perfect and able to throw the
fullest necessary light on all matters which any aspiring seeker after
knowledge can possibly seek to be enlightened on.
4. It is thus in the fitness of things that the Vedas include (i) Ayurveda
(anatomy, physiology, hygiene, sanitary science, medical science, surgery
etc., etc.,) not for the purpose of achieving perfect health and strength
in the after-death future but in order to attain them here and now in
our present physical bodies; (ii) Dhanuveda (archery and other military
sciences) not for fighting with one another after our transportation
to heaven but in order to quell and subdue all invaders from abroad
and all insurgents from within; (iii) Gandharva Veda (the science and
art of music) and (iv) Sthapatya Veda (engineering, architecture etc.,
and all branches of mathematics in general). All these subjects, be
it noted, are inherent parts of the Vedas i.e. are reckoned as "spiritual"
studies and catered for as such therein.
5. Similar is the case with regard to the Vedangas (i.e. grammar, prosody,
astronomy, lexicography etc., etc.,) which, according to the Indian
cultural perceptions, are also inherent parts and subjects of Vedic
(i.e. Religious) study.
6. As a direct and unshirkable consequence of this analytical and grammatical
study of the real connotation and full implications of the word "Veda"
and owing to various other historical causes of a personal character
(into details of which we need not now enter), we have been from our
very early childhood, most earnestly and actively striving to study
the Vedas critically from this stand-point and to realise and prove
to ourselves (and to others) the correctness (or otherwise) of the derivative
meaning in question.
7. There were, too, certain personal historical reasons why in our quest
for the discovering of all learning in all its departments, branches,
sub-branches etc., in the Vedas, our gaze was riveted mainly on ethics,
psychology and metaphysics on the one hand and on the "positive" sciences
and especially mathematics on the other.
8. And the contemptuous or, at best patronising attitude adopted by
some so-called Orientalists, Indologists, antiquarians, research-scholars
etc., who condemned, or light-heartedly, nay; irresponsibly, frivolously
and flippantly dismissed, several abstruse-looking and recondite parts
of the Vedas as "sheer-nonsense"- or as "infant-humanity's prattle",
and so on, merely added fuel to the fire (so to speak) and further confirmed
and strengthened our resolute determination to unravel the too-long
hidden mysteries of philosophy and science contained in India's Vedic
lore, with the consequence that, after eight years of concentrated contemplation
in forest-solitude, we were at long last able to recover the long lost
keys which alone could unlock the portals thereof.
9. And we were agreeably astonished and intensely gratified to find
that exceedingly tough mathematical problems (which the mathematically
most advanced present day Western scientific world had spent huge lots
of time, energy and money on and which even now it solves with the utmost
difficulty and after vast labour and involving large numbers of difficult,
tedious and cumbersome "steps" of working) can be easily and readily
solved with the help of these ultra-easy Vedic Sutras (or mathematical
aphorisms) contained in the Parishishta (the Appendix-portion) of the
ATHARVAVEDA in a few simple steps and by methods which can be conscientiously
described as mere "mental arithmetic".
10. Ever since (i.e. since several decades ago), we have been carrying
on an incessant and strenuous campaign for the India-wide diffusion
of all this scientific knowledge, by means of lectures, blackboard-demonstrations,
regular classes and so on in schools, colleges, universities etc., all
over the country and have been astounding our audiences everywhere with
the wonder and marvels not to say, miracles of Indian Vedic Mathematics.
11. We were thus at last enabled to succeed in attracting the more than
passing attention of the authorities of several Indian universities
to this subject. And, in 1952, the Nagpur University not merely had
a few lectures and blackboard-demonstrations given but also arranged
for our holding regular classes in Vedic Mathematics (in the University's
Convocation Hall) for the benefit of all in general and especially of
the University and college professors of mathematics, physics etc.
12. And, consequently, the educationists and the cream of the English
educated section of the people including the highest officials (e.g.
the high-court judges, the ministers etc.,) and the general public as
such were all highly impressed; nay, thrilled, wonder-struck and flabbergasted!
and not only the newspapers but even the University's official reports
described the tremendous sensation caused thereby in superlatively eulogistic
terms; and the papers began to refer to us as " the Octogenarian Jagadguru
Shankaracharya who had taken Nagpur by storm with his Vedic Mathematics",
and so on!
13. It is manifestly impossible, in the course of a short note (in the
nature of a "trailer"), to give a full, detailed, thorough-going, comprehensive
and exhaustive description of the unique features and startling characteristics
of all the mathematical lore in question. This can and will be done
in the subsequent volumes of this series (dealing seriatim and in extenso
with all the various portions of all the various branches of mathematics).
14. We may, however, at this point, draw the earnest attention of everyone
concerned to the following salient items thereof:-
(i) The Sutras (aphorisms) apply to and cover each and every part of
each and every chapter of each and every branch of mathematics (including
arithmetic, algebra, geometry- plane and solid, trigonometry- plane
and spherical, conics- geometrical and analytical, astronomy, calculus-
differential and integral etc., etc. In fact, there is no part of mathematics,
pure or applied, which is beyond their jurisdiction;
(ii) The Sutras are easy to understand, easy to apply and easy to remember;
and the whole work can be truthfully summarised in one word "mental"!
(iii) Even as regards complex problems involving a good number of mathematical
operations (consecutively or even simultaneously to be performed), the
time taken by the Vedic method will be a third, a fourth, a tenth or
even a much smaller fraction of time required according to the modern
(i.e. current) Western methods;
(iv) And, in some very important and striking cases, sums requiring
30, 50, 100 or even more numerous and cumbrous "steps" of working (according
to the current Western methods) can be answered in a single and simple
step of work by the Vedic method! And little children (of only 10 or
12 years of age) merely look at the sums written on the blackboard (on
the platform) and immediately shout out and dictate the answers from
the body of the convocation hall (or other venue of demonstration).
And this is because, as a matter of fact, each digit automatically yields
its predecessor and its successor! and the children have merely to go
on tossing off (or reeling off) the digits one after another (forwards
or backwards) by mere mental arithmetic (without needing pen or pencil,
paper or slate etc)!
(v) On seeing this kind of work actually being performed by the little
children, the doctors, professors and other "big-guns" of mathematics
are wonder struck and exclaim:- "Is this mathematics or magic?" And
we invariably answer and say: "It is both. It is magic until you understand
it; and it is mathematics thereafter"; and then we proceed to substantiate
and prove the correctness of this reply of ours! And
(vi) as regards the time required by the students for mastering the
whole course of Vedic Mathematics as applied to all its branches, we
need merely state from our actual experience that 8 months (or 12 months)
at an average rate of 2 or 3 hours per day should suffice for completing
the whole course of mathematical studies on these Vedic lines instead
of 15 or 20 years required according to the existing systems of Indian
and also of foreign universities.
15. In this connection, it is a gratifying fact that unlike some so-called
Indologists (of the type hereinabove referred to) there have been some
great modern mathematicians and historians of mathematics (like Prof.
G. P. Halstead, Professor Ginsburg, Prof. De Morgan, Prof. Hutton etc.,)
who have, as truth-seekers and truth-lovers, evinced a truly scientific
attitude and frankly expressed their intense and whole-hearted appreciation
of ancient India's grand and glorious contributions to the progress
of mathematical knowledge (in the Western hemisphere and elsewhere).
16. The following few excerpts from the published writings of some universally
acknowledged authorities in the domain of the history of mathematics,
will speak eloquently for themselves:-
(i) On page 20 of his book "On the Foundation and Technique of Arithmetic",
we find Prof. G. P. Halstead saying "The importance of the creation
of the zero mark can never be exaggerated. This giving of airy nothing
not merely a local habitation and a name, a picture but helpful power
is the characteristic of the Hindu race whence it sprang. It is like
coining the Nirvana into dynamos. No single mathematical creation has
been more potent for the general on-go of intelligence and power".
(ii) In this connection, in his splendid treatise on "The present mode
of expressing numbers" (the Indian Historical Quarterly Vol. 3, pages
530-540) B. B. Dutta says "The Hindus adopted the decimal scale very
early. The numerical language of no other nation is so scientific and
has attained as high a state of perfection as that of the ancient Hindus.
In symbolism they succeeded with ten signs to express any number most
elegantly and simply. It is this beauty of the Hindu numerical notation
which attracted the attention of all the civilised peoples of the world
and charmed them to adopt it".
(iii) In this very context, Prof. Ginsburg says:- "The Hindu notation
was carried to Arabia about 770 A.D. by a Hindu scholar named KANKA
who was invited from Ujjain to the famous court of Baghdad by the Abbaside
Khalif Al-MANSUR. Kanka taught Hindu astronomy and mathematics to the
Arabian scholars; and, with his help, they translated into Arabic the
Brahma-Sphuta-Siddhanta of Brahma Gupta. The recent discovery by the
French savant M. F. NAU proves that the Hindu numerals were well known
and much appreciated in Syria about the middle of the 7th Century A.D.
(GINSBURG'S "New light on our numerals", Bulletin of the American Mathematical
Society, Second Series, Vol. 25, pages 366-369).
(iv) On this point, we find B. B. Dutta further saying: "From Arabia,
the numerals slowly marched towards the West through Egypt and Northern
Arabia; and they finally entered Europe in the 11th Century. The Europeans
called them the Arabic notations, because they received them from the
Arabs. But the Arabs themselves, the Eastern as well as the Western,
have unanimously called them the Hindu figures. (Al-Arqan-Al-Hindu)."
17. The above-cited passages are, however, in connection with, and in
appreciation of India's invention of the "ZERO" mark and her contributions
of the 7th century A.D. and later to world mathematical knowledge.
In the light , however, of the hereinabove given detailed description
of the unique merits and characteristic excellences of the still earlier
Vedic Sutras dealt with in the 16 volumes of this series, the conscientious
(truth-loving and truth-telling) historians of mathematics (of the lofty
eminence of Prof. De Morgan etc.) have not been guilty of even the least
exaggeration in their candid admission that "even the highest and farthest
reaches of modern Western mathematics have not yet brought the Western
world even to the threshold of Ancient Indian Vedic Mathematics".
18. It is our earnest aim and aspiration, in these 16 volumes, to explain
and expound the contents of the Vedic Mathematical Sutras and bring
them within the easy intellectual reach of every seeker after mathematical
knowledge.
