Now this sun is described as the eye of all planets, yac-cakṣur eṣa sakala-grahāṇāṁ. Sakala means "All the planets." The eyes . . . real eye is the sun, because without sunshine we cannot see. In this planet or any planet you go, as soon as there is sunshine you can see; otherwise you cannot see. Therefore real eye is the sun. Yac-cakṣur eṣa savitā sakala-grahāṇāṁ. Rājā: he is the king, samasta-sura-mūrtir, of all the demigods. There in the sunshine, there is a president. As you have got a president here, similarly the sun planet there is president. His name is Vivasvān.
So we have got such knowledge. We can give you the name of the sun planet, the president of the sun planet, his address. (laughter) We can give you the address of God, Kṛṣṇa, His features, His activities. This is perfect knowledge. Simply vague idea, that is not knowledge. Everything is there: what God is working, how He is acting, what is His address, who is His father, who is His mother—everything. It is so . . . therefore it is called rāja-vidyā, king of all knowledge. You get everything, completely, rāja-vidyā; nothing vague. Nothing as speculation. Act . . . active, everything. Therefore it is pavitram. Uttamam. In the material knowledge, your knowledge is never perfect. Therefore it is called uttamam, "above this material knowledge," transcendental, aprākṛta.
