“तथा च स्मर्यते योजनानां सहस्त्रं द्वे द्वे शते द्वे च योजने एकेन निमिषार्धेन क्रममाण नमोऽस्तुते॥”
“[O Sun,] bow to you, who traverses 2,202 yojanas in half a nimesha.”
Rigveda (4,000 BCE)
Hindus have made many astute observations nearly 6,000 years ago through the power of yoga. Instead of relying on external instruments, the mind itself was made the instrument, extending it beyond the range of normal human perception, giving the deep insight (drshta) into the underlying nature of the universe (hence the western name “seers”).
One such example, is the the speed of light to an accuracy of 0.1% (and the concept of light-years – the distance light travels in one year) almost 6,000 years before the discovery of the same by James Bradley (1729ce).
“…One such book is the celebrated commentary on the Rigveda by Sayana (c. 1315-1387), a minister in the court of King Bukka of the Vijayanagar Empire in South India. In a hymn addressed to the sun, he says that it is “remembered that the sun traverses 2,202 yojanas in half a nimesha.”
This statement could either relate to the speed of the sun or to that of light. The units are well known. For example, the Indian epic “Mahabharata” … defines 1 nimesha to be equal to 16/75.3 seconds; 1 yojana is about 9 miles.
Substituting in Sayana’s statement we get 186,536 miles per second. ”
Sun/Light travels 2,202 yognas in 1/2 nimisha =
= (2202 x 9 miles) x 2 in 1 nimisha
= 39636 miles in 1 nimisha
= 39636 x 75.3/16 in one second
= 186,536 miles/sec
= 300,201 km/sec = the speed of light as known today accurate to 0.1% !
