Why Are Buddhas Reluctant to Remain and Teach the Dharma Upon Attaining Buddhahood in Saha-like Worlds?

When you attain the third and fourth stages of enlightenment, eradicating the afflictions of greed, hatred, and delusion, your perspective on sentient beings will be entirely different from what it is now. You will refrain from saying many things, for it would be futile to say anything—much like a university professor observing kindergarten children, feeling they are truly beyond instruction. When you achieve Buddhahood and behold the multitudes of sentient beings, engulfed in vast swathes of greed, hatred, and delusion, utterly foolish, you will likewise feel that expounding the profound Dharma to such beings would be unimaginable—no better than playing the lute to a cow. When you are on the same level as sentient beings, you perceive nothing unusual about them. But once you transcend that level and look down from above, that state of mind is beyond your comprehension and imagination, rendering words useless. The Buddhas, Bodhisattvas, and sages have no true companions, for sentient beings are unable to comprehend, much less experience, the sages' state of mind.
