निताइ dasa
Nitai's servant's servant
While on the subject, I would like to draw a clear distinction between the four Vedas, the Vedanga (auxillary texts) and the Purana. Let us not mix them all up into one single body of scripture - for they are not. In other words, Baudhayana's sutras - though held in high regard - are not Veda.
It depends on the school. For us (and Kalyanji) all of them fall into one body of knowledge collectively referred the Vedas. That is why the field is referred to as Vedic Mathematics. We do not subscribe to the limited scope of all the four Vedas. Vedas refers to us as all 4 Vedas, along with Upavedas, as well as the Puranas (and Upapuranas) and that is the definition I am basing my argument. Shastra or scripture (called Sabda) refers all of them.
. A prayer authored by a poet is far removed by a statement that attempts to provide the speed of the Sun or light. Therefore, we not discussing the Veda, but Sayana, who was from the 14th Century CE and this is not strictly relevant to the topic of Vedic knowledge.
My question is how the heck Sayana was able to figure out light speed, without the instruments we had today. Also in his commentary he says "it is remembered" which means that astrologers knew this fact previously. Again this shows signs of a highly advanced civilization, far more advanced than any in that time, even materially.
n Pythagoras, the general acceptance is that the properties of a right angled triangle were known well before his time, discovered independently around the world by different civilizations. Pythagoras is known to have traveled through Egypt and this theorom was known to Egyptians thousands of years before his time (~2400 BC).
Again would like to see proof.
As you agree, this does not say that the Earth is spherical.
It certainly implies it. Such statements are not possible if they simply saw earth as flat.
