“With these material senses, you cannot experience directly what is the form of the Lord, what is His quality, what does He do. So many things we want to know about the Supreme. But śāstra describes the qualities of the Lord, the form of the Lord, the activities of the Lord. You can learn. Śāstra-yonitvāt. Yoni means source, source. Śāstra-yonitvāt. Śāstra-cakṣus. Your eyes should be the śāstra. Not these blunt eyes. Everything we also experience by śāstra, by book.

So we have to see through the authorized books the description which is beyond our perception.”  Srila Prabhupada Bhagavad-gītā 2.18 — London, August 24, 1973
