two taps

Spiritual life means to turn off the tap spewing filthy liquid and turn on the tap with clear water.

Maya means only mud will come out of the tap, no matter what you do. Even turning it off doesn't work.

Krsna means the pure water of unalloyed devotional service will come out of the tap. But it takes time to turn the other tap off and for the accumulated dirty muck to be washed off.
