4. The Great Rishis
Rishi means ‘SEER’: The discoverer
Hindu Rishis were
– philosophers
– mathematicians
– scientists
They made fundamental discoveries
All reported in the great Vedic literature
5. The Puzzle
Books are written by
civilised people
Civilisations existed at
banks of rivers
Where is your river?
Aryan must have come
from outside India
Aryans - not a race. It
means ‘noble people’
River Saraswati
Now extinct but its path
has been traced by satellite
photography
Myth of Aryan invasion
has been smashed
6. Sage Atharvan: Discoverer of Fire
Rishi of Atharva Veda
4000 BC or even earlier
“The sage Atharvan extracted the
agni(fire)” - Rig VI-16-13
“The priests churn for agni as
was done by Atharvan” - Rig X-21-5
Prometheus = Pra + Mantha
In Sanskrit ‘by’ ‘Churning’
Greek mythology

stole fire from
heaven

9. Dimensions of Yuga
“With the consonants they fill the nights, with the
vowels the days” - Aitareya Aranyaka
Verse Type Syllables No. of Verses Total
Brhati 36 12000 432000
Pankti 40 10800 432000
Kali yuga = 432000 syllables = 432000 years
Dwapara yuga = 2 x Kaliyuga = 864000 years
Tretaa yuga = 3 x Kaliyuga = 1296000 years
Sata yuga = 4 x Kaliyuga = 1728000 years
Total = Chaturyugi = 10 x kaliyuga = 4320000 years
One divine day = 1000 Chaturyugi = 4320 million years
Divine Day = Creation Divine Night = Dissolution
10. One God - 3 Metaphorical Forms
Kala Purusha (Time) - Omniscient
Veda Purusha (Knowledge) - Omnipresent
Yajna Purusha (Action) - Omnipotent

13. Symposium on Man and Disease:
The Question
“What is the source of the
man and the disease?
Do both come from the
same source?
King Vamaka of Kashi
14. Pariksi Maudgalya
“Man is born of the
Spirit, likewise all
diseases are born of
the Spirit. The
Spirit is the source
of all”
15. Sage Saraloma
“No. The Spirit dislikes
pain. It would never on
its own accord yoke itself
to painful diseases. The
real cause is the mind
when its engrossed by
passion and ignorance”
16. Varyovida
“Mind by itself can’t
cause any thing.
Without a body,
there cannot be any
disease, not even the
mind. All life started
from water. Water is
the cause of all
diseases.”
17. Hiranyaksha
“Every thing does not depend on water. I am
aware of air-borne diseases. Man is the
result of the 5 physical elements and
consciousness.”
18. Sage Shaunaka
“How can you have the 5 elements and the
consciousness without a creator or a father
and mother? Therefore, parents are the
origin of both, the individual and the
disease.”
19. Bhadrakapya
“No. Blind are not born
of the blind. And you
cannot tell who the first
parents were. Creatures
are born of the merits
of action and from the
actions arise the
diseases.”
20. Rishi Bharadwaja
“I disagree. The doer always proceeds the
deed. Nature alone is the cause. Roughness
of the earth, fluidity of water, mobility of air
and heat of fire.”
21. Kankayana
“Effort or lack of
effort is not
determined by the
course of nature.
Brahmaa, the
Creator of the
universe, is the
source of all”
22. Aterya
“No. Brahmaa cannot give pain to his own
children. Evolution has taken place over
time. So time is the cause of creation of
Man and disease.”
23. Punarvasu’s Decision
“Truth is hard to find by taking
sides in a debate.
“The wholesome combination of
the physical elements gives rise to
the well being of Man.
Unwholesome combination leads
to disease”
Balanced elements = At ease with each other
Unbalanced elements = not at ease = dis +
ease = disease
Now known as the Ayur Veda

28. Kanada: First Expounder of Law
of Causation and Atomic Theory
Ten books known as ‘Vaisesika Darshana’
About 1900 years old
First to explore the relation between ‘Cause
and Effect’
Identified atoms (Parmanu) as the build
blocks of matter
Defined chemical action (Paka)
29. Great Mathematicians
Medhatithi- Extended numerals to billions
Aryabhata- laid foundations of Algebra
Lagadha - Rationalised Astronomy
Baudhayana - The first great Geometer
30. Science of Geometry
‘Sulbha Sutras’ - Sulb means to measure
Bodhyana’s sutras are 2800 years old
Used in the construction of altars for yajna
Discovered the Pythagorus theorem before
Pythagorus
Formula to draw a circle with same area of
a square
Computed square root of 2 = 1.414213
31. Pythagorus Theorem
“The diagonal of a rectangle produces area
which its length and breadth produce
separately” - BS I-I-48
a
b
c
a2 + b2 = c2
32. Transfer a Square into a Circle
“If you wish to circle a
square, draw half its
diagonal about its centre
towards the North-East
line; then describe a circle
together with the one-
third of that which lies
outside the square”
- BS I-I-58
N
W
33. Square Root of 2
“Increase the measure by its third part, and
again by the fourth part less by the thirty-
fourth part of itself” - BS I-61-2
D = a + a/3 + a/(3x4) - a/(3x4x34)
2 = 1 + 1/3 + 1/(3x4) - 1/(3x4x34) = 1.4142
34. Vedic Mathematics
The ‘Parisista’ (appendix section) of the
Atharva Veda contains 16 ‘Sutras’
(formulae) that turn difficult Mathematics
into simple and fun calculations.
The material is mostly based on ‘Vedic Mathematics’
by Sri Bharati Krishna Tirthaji of Govardan Pitha, we
are grateful to him for revealing the cryptic mysteries
of the Sutras.
36. Conclusions
Many branches of modern science
originated in India (Bharat)
There is not much awareness about this rich
heritage of India
Knowledge of Sanskrit is essential to
discover our own riches
37. Good News
You can learn Sanskrit by correspondence
course
4 stages of 10 lessons each leading to a
diploma
