(Krishna's spiritual and material worlds)
"Don't waste your time simply, 'What is this? What is that? What is this? What is that?' Just immediately take shelter of the Supreme Lord. That is your immediate necessity. Because we do not know when death will come. So this is an opportunity. Suppose if you do something and if you are given ultimatum, the deadline, that 'Within five minutes you must finish,' similarly, this spot of life, in the comparison of our eternal life, it is only five minutes. But if five minutes is wasted simply for eating, sleeping, and for a little comfort of this body, and our mission is forgotten, oh, it is simply suicidal for you. Therefore Bhāgavata says, bhaktim udasya. Giving up the devotional service, Kṛṣṇa consciousness, if one is foolishly simply engaged in understanding 'What is this? What is that...?' That will be understood. Yasmin vijñāte sarvam etaṁ vijñātaṁ bhavati. If you understand Kṛṣṇa, if you understand the Supreme Absolute Truth, then there will be nothing unknown. Everything will be known because He is everything."
(Srila Prabhupada Lecture, San Francisco, January 21, 1967)
