Swept away by the current of the four powerful rivers, tied by the tight bonds of karma, so hard to undo, caught in the iron net of self-grasping, completely enveloped by the total darkness of ignorance, endlessly reborn in cyclic existence, ceaselessly tormented by the three sufferings – thinking that all mothers are in such a condition, generate the supreme mind of enlightenment.
