The Buddha's divine-eye and knowledge of others' spiritual potential was working fine. He foresaw that due to their previous unwholesome kamma they were destined to die in this way. That is why he left strict instructions with Ānanda that he should not be disturbed for a fortnight. It is also why he gave them a meditation object that would develop disgust and loathing for the physical body.pink_trike wrote:What happened to the Buddha's "divine eye" that could supposedly see a perfect stranger's former and future lives? Why didn't he know what happened, and why didn't he foresee this mass suicide inspired by his teachings?
In the case of Mahā-Moggallāna's murder too, the Buddha could not intervene to prevent it. That does not mean that he did not know it was going to happen.
Some kammas are like a ball shot along a billiard table — it's course can be altered by hitting it with another one.
Some kammas are like a bullet shot from a rifle — it's trajectory can be deflected by strong armour, but one cannot dodge it or see it coming.
Other kammas are like a large meteor. Not even a nuclear bomb can deflect it from its course.
