Srila Prabhupada explains that when a tiger deals with it’s own cubs, it picks them up with its mouth just like you see the cat lift up the kitten. But that lifting with the mouth is filled with motherly affection moving them from one place to the other, but when the tiger jumps on the prey whether it’s a deer, zebra or whatever, it might be that it bites them with its mouth. But that is totally a different bite. So the law of Karma is like the tiger on the prey, like the cat on the mouse.
But when you take shelter of Krishna then what appears to be Karma is actually Krishna personally taking charge of the devotee. It is like the cat or the tiger taking the cub, the kid, by the mouth, simply for purification, for our remembrance.
So whether we want to be under the care of Krishna or under the care of the illusory energy and the stringent lat of Karma, that’s up to us to decide. When we are under the care of Krishna and we do devotional service, we feel very blissful. We just have to be a little careful. We have to go on learning and trying to practice responsibly, remaining humble. We have to be aware of what mistakes we are making and try to correct them, because we are responsible for them.
