'Purifying and regulating the three karmas', and so forth: for example, just as the great earth generates and grows all grasses and trees, both good and bad, if one cultivates that earth, then good grasses will grow. The three karmas of sentient beings can generate good and evil, and are therefore compared to the earth. Cultivating the earth of the three karmas, leaving behind all faults and evils, and growing good practices, one is therefore able to give rise to compassion and benefit conscious beings.
