The same example as I gave sometime, that you learn how to drive aeroplane. So you go high in the sky. But if you are in danger, no other aeroplane can help you. You are finished. Therefore you must be a very careful pilot to take care of yourself.
Similarly, in this material world everyone individually has to take care of himself, how he can be saved from the clutches of maya. That is Krsna consciousness movement. A teacher can give you hints. The acarya can give you hints that “You can be saved in this way.” But the execution of the duties, that is in your hand. If you perform the spiritual duties rightly, then you are saved. Otherwise, even acarya gives you instruction, if you don’t follow, so how he can save you? He can save you by instruction, by his mercy, as much as possible. But you have to take it in your hands seriously.
