Question: “Sentient beings have numerous kinds of sufferings. Why would the Buddha not use his divine power to let all sentient beings attain liberation?”
Reply: “Everything can be rectified. Let’s resolve that from a coarser view. For instance, there are various fetters, which can be subsumed under the three poisons.”
Question: “By saying that ‘A blind person can regain his vision,’ is sufficient. Why deliberately say that a person is “born blind” instead?'"
Reply: “People who were ‘born blind’ was due to grievous karma committed in their previous lives. Even a serious offender can regain his vision. Let alone minor offenders."
Question: “What kind of grievous karma from previous lives will cause one to be a ‘born blind’ person?”
Reply: “Should one damage or gouge sentient beings’ eyes, or destroy the eyes of correct views, and say that there is no crime nor virtue. In these cases, such a person will descend into hell when he dies, and after serving the terms there, he will be ‘born blind’ at birth.”
Furthermore, should one steal the bright pearls and various lights and lamps from the Buddha’s stupa; steal the jewel and lights from the arhats’ and pratyekabuddhas’ stupa; or steal the lights from other virtuous persons, these unwholesome deeds from his previous lives are the karmic causes and conditions that will result in his blindness.
However, when one becomes blind in this life due to illness or fighting, these illnesses or fighting are the causes and conditions of the current life that cause him blindness.
Furthermore, there are these ninety-six kinds of eye sicknesses that even the Janaka King of medicine cannot cure. Only the Buddha can replenish the vision of these patients and let them see again. In such a manner, the Buddha will aid the patients to regain their vision before obtaining the wisdom-eye. Similarly, the deaf will regain their hearing in the same way.”
