Why Are Buddhas Reluctant to Remain and Expound the Dharma Upon Attaining Buddhahood in Worlds Like the Saha World?

When you attain the Third and Fourth Fruits, eradicating the defilements of greed, hatred, and delusion, your perspective on sentient beings will differ entirely from your current view. You will refrain from saying many things you might say now, because it would be pointless—much like a university professor observing kindergarten children might deem them unteachable. When you achieve Buddhahood and behold the multitudes of sentient beings, seeing vast fields of greed, hatred, and delusion—such profound ignorance—you will similarly feel that expounding the profound Dharma to such beings would be inconceivable, no different from casting pearls before swine. When you are on the same level as ordinary beings, you cannot perceive their true state. But once you transcend that level and look down from above, that state of mind is beyond your current comprehension or imagination, rendering any attempt to explain it futile. The Buddhas, Bodhisattvas, and sages have no kindred spirits and endure profound solitude, for sentient beings cannot comprehend, much less experience, the enlightened mind of the sages.
