Moved by compassion, Bodhisattvas take the vow to liberate all sentient beings. Then by overcoming their self-centered outlook, they engage eagerly and continuously in the very difficult practices of accumulating merit and insight. Having entered into this practice, they will certainly complete the collection of merit and insight.
Accomplishing the accumulation of merit and insight is like having omniscience itself in the palm of your hand. Therefore, since compassion is the only root of the omniscience of the Buddhas, you should become familiar with this practice from the very beginning.
