तरणिर्विश्वदर्शतो जयोतिष्क्र्दसि सूर्य | विश्वमा भासिरोचनम |
taranirviśvadarśato jyotishkridasi sūrya | viśvamā bhāsirocanam ||
This means “Swift and all beautiful art thou, O Surya (Sun), maker of the light, illuminating all the radiant realm.”
Exlpaining this verse in his Rig Veda commentary, Sayana, who was a minister in the court of Bukka of the great Vijayanagar Empire of Karnataka in South India (in early 14th century), says:
tatha ca smaryate yojananam. sahasre dve dve sate dve ca yojane ekena nimishardhena kramaman.
This means “It is remembered here that Sun (light) traverses 2,202 yojanas in half a nimisha.”
Note: Nimisharda = half of a nimisha In the vedas Yojana is a unit of distance and Nimisha is a unit of time.
Unit of Vedic Time: Nimisha
The Moksha Dharma Parva of Shanti Parva in Mahabharata describes Nimisha as follows: 15 Nimisha = 1 Kastha 30 Kashta = 1 Kala 30.3 Kala = 1 Muhurta 30 Muhurtas = 1 Diva-Ratri (Day-Night) We know Day-Night is 24 hours So we get 24 hours = 30 x 30.3 x 30 x 15 nimisha in other words 409050 nimisha We know 1 hour = 60 x 60 = 3600 seconds So 24 hours = 24 x 3600 seconds = 409,050 nimisha 409,050 nimisha = 86,400 seconds 1 nimisha = 0.2112 seconds (This is a recursive decimal. The wink of an eye is equal to 0.2112 seconds.) 1/2 nimisha = 0.1056 seconds
Unit of Vedic Distance: Yojana
Yojana is defined in Chapter 6 of Book 1 of the ancient vedic text “Vishnu Purana” as follows:
10 ParamAnus = 1 Parasúkshma 10 Parasúkshmas = 1 Trasarenu 10 Trasarenus = 1 Mahírajas (particle of dust) 10 Mahírajas= 1 Bálágra (hair’s point) 10 Bálágra = 1 Likhsha 10 Likhsha= 1 Yuka 10 Yukas = 1 Yavodara (heart of barley) 10 Yavodaras = 1 Yava (barley grain of middle size) 10 Yava = 1 Angula (1.89 cm or approx 3/4 inch) 6 fingers = 1 Pada (the breadth of it) 2 Padas = 1 Vitasti (span) 2 Vitasti = 1 Hasta (cubit) 4 Hastas = a Dhanu, a Danda, or pauruSa (a man’s height), or 2 Nárikás = 6 feet 2,000 Dhanus = 1 Gavyuti (distance to which a cow’s call or lowing can be heard) = 12,000 feet 4 Gavyutis = 1 Yojana = 9.09 miles
Calculation of the Speed of Light from the Rig Veda:
So now we can calculate what is the value of the speed of light in modern units based on the value given as 2202 yojanas in 1/2 nimisha
= 2,202 x 9.09 miles per 0.1056 seconds = 20,016.18 miles per 0.1056 seconds = 189,547 miles per second
As per the Rig Veda the speed of light is 189,547 miles per second. As per modern science the speed of light is 186,000 miles per second!
