(Lord Sri Krishna)
Devotee: Sometimes it's difficult as devotees for us to know whether we're doing the right thing or whether we're just speculating.
Prabhupāda: And therefore you have to consult your guru.
Devotee (2): It's because we are not surrendered.
Devotee: But even in small things, just day-to-day activities...
Prabhupāda: There is no small thing. Everything big thing for a devotee.
Devotee: I've discovered, Śrīla Prabhupāda, the way to do that, of course, is to read your books.
Devotee (3): By reading your books, then all of the...
Prabhupāda: Therefore the books are there.
Devotee (3): Even practical, everything...
Devotee (2): But without attitude of devotion, nothing will work.
Devotee (2): Attitude of devotion must be there.
Prabhupāda: The attitude, devotion, is there. Otherwise why one should come to our camp? But it must be properly utilized. It should not be misused. If you go to school and if you don't read books, then you'll fail in the examination.
Devotee (4): But the attitude of devotion should be there every moment, so everything...
Devotee (4): ...is very meaningful. Everything is a big thing. When we go out we should realize we're doing it for Kṛṣṇa.
Prabhupāda: That is said, man-manā. Think of Kṛṣṇa; He'll guide you. Very easy thing. Man-manā. Always think of Kṛṣṇa, then there is no question of falling down. Man-manā bhava mad-bhakto mad-yājī māṁ namaskuru (BG 18.65). These four things, if strictly done, he is safe. He is safe. Always think of Kṛṣṇa, become His devotee, offer Him obeisances and... Man-manā bhava mad-bhakto mad-yājī, and worship Him. This is Deity worship. That will engage in always in thinking, in offering obeisances. And if we strictly follow only these, these four principles, mām evaiṣyasi asaṁśayaḥ (BG 18.68): "You are coming back to Me without any doubt." But instead of thinking Kṛṣṇa, we are thinking something else, planning something, misusing independence.
