A person who acts exactly according to the tenets of scripture is called sastra-caksus. Sastra-caksus means one who sees through the eyes of the authorized scriptures. Actually, any man of knowledge and experience should see everything through these books. For example, with our naked eye we perceive the sun globe simply as some glaring substance, but when we see through authorized books of science and other literature, we can understand how much greater the sun globe is than this earth and how powerful it is. So seeing things through the naked eye is not actually seeing. Seeing things through the authorized books or authorized teachers is the correct way to see. So, although Krsna is the Supreme Personality of Godhead and can see all that is past, present and future, to teach the people in general He used to always refer to the scriptures. For example, in the Bhagavad-gita, although Krsna was speaking as the supreme authority, He still mentioned and quoted Vedanta-sutra as authority. There is a statement in the Srimad-Bhagavatam wherein a person jokingly says that Krsna, the enemy of Kamsa, is known as the seer through the sastras. In order to establish His authority, however, He is now engaged in seeing the gopis, whereby the gopis are becoming maddened.
