When the Sixth Patriarch Huineng first met Master Yinzong at Faxing Temple in Guangzhou, Master Yinzong asked the Sixth Patriarch Huineng: "What did the Fifth Patriarch teach you?" Huineng, the Sixth Patriarch, said: "It's not about teaching, it's just about how to see your own mind, and it doesn't involve meditation and liberation." Master Yinzong asked, "Why didn't it involve meditation and liberation?" The Sixth Patriarch Huineng said: " Because it is the Dharma of difference, not the Dharma. The Dharma is without distinction.” Master Yinzong asked again: “What is the Dharma without distinction?” The Sixth Patriarch Huineng said: “Master, you were teaching the Mahāparinirvāṇa Sūtra yourself. At the time, the scriptures said, "Seeing the Buddha's nature is the Dharma without distinction." Just like in the "Mahāparinirvāṇa Sūtra", the Noble Virtue King Bodhisattva asked the Buddha: Does a person who commits a serious crime destroy the Buddha-nature of the good root? The Buddha said: There are two kinds of good roots. One is permanent and the other is impermanent. The Buddha-nature is neither permanent nor impermanent, so there is no destroy of the Buddha-nature. This is the Dharma without distinction. One is good and the other is bad. Buddha-nature is neither good nor bad, it is indifference. For the realm of perception, ordinary people feel the difference, while wise men understand the real situation, and their minds do not reflect any difference. This is the indiscriminate nature of mind. The indiscriminate nature of mind is Buddha nature."
When Universal Light Tathagata was alive, Shanhui was an immortal. Shanhui took refuge in Buddhism and became enlightened when he met Universal Light Buddha. In order to get rid of Shanhui's fairy clothes (deerskin coat and fairy hair bun), Universal Light Buddha created a puddle of mud on the ground. Shanhui was afraid that Universal Light Tathagata's feet would step on the mud, so he covered the mud with his deerskin coat, but it was not enough to cover the mud, so Shanhui spread his bun and covered the mud with his hair. Universal Light Buddha walked through the coat and hair, and said: "You will become a Buddha in the future, and the Buddha's name is Sakyamuni. You will become a Buddha in the evil world of five turbidities, and it will not be difficult for you to save all living beings at that time."
Universal Light Tathagata is the Dipankara Buddha, and Shanhui is the previous life of Sakyamuni Buddha.
In the ground of cause, Shanhui covered the mud with his coat and hair, and in the ground of fruit, Buddha Shakyamuni used his wisdom to save all living beings from the evil world of five turbidities. Karma can never go wrong.
Unsurpassed Bodhi, one must know one's own mind, see one's own nature, neither arise nor perish. At all times, in every thought, one must observe one's own heart, not dwelling on any dharma, a sincere heart sees that everything is truth, and any state can be understood naturally. The heart of true wisdom is the truth. If you see it like this, it is the self-nature of the supreme Bodhi.
Impermanence, a Buddhist term, is an antonym of constant. The literal meaning is variation, which means that all things in the world will eventually change, and there is no permanent existence. Impermanence says that everything is unreal and can not last for ever. All things are born of cause and condition, and gradually become corrupted, so they are called impermanence.
Fools in the world do not know cause and effect. Once they see that people who do good deeds suffer misfortune, they say that doing good deeds is useless. Once they see that those who do evil things are blessed, they say that evil things can be done. They don't know that the arrival of misfortune and blessing has different circumstances, and sooner or later is uncertain. Doing good and evil is like sowing grain. If you do good deeds in this life, but the bad karma in the previous life is heavy, then the bad karma in the previous life will arrive before the good retribution in this life comes. Just like a person who didn't plant millet last year, although he worked hard this year, he will inevitably have no food before the harvest. In this case, there is no grain not because there was no hard work this year, but because there was no sowing last year. If you cultivate hard this year, you will have grain next year after harvesting. The evildoer has not yet received calamity, because he still has the remaining blessings that have not been exhausted. It's like a person who worked hard last year to cultivate, but didn't cultivate this year, so he won't be hungry because he still has the surplus food from last year. When the grain is eaten, there will be no food because there is no cultivation this year. Therefore, you should know that if a good person receives evil rewards and stops doing good deeds, then the evil rewards will be more serious, because doing good deeds has already reduced the evil rewards; if evil people get good rewards, if they stop doing evil, the good rewards will be greater，because of doing evil, the good rewards that should have been received have been reduced. You get what you sow. If the sound is soft, the echo is soft; if the shape is straight, the shadow is straight. These are things that people have seen with their own eyes and can believe without a doubt. The principle of cause and effect covers all principles in the world and beyond.
Rejoicing means that when a person sees others doing good deeds, teaching good dharmas, and achieving success, he will be happy accordingly. Rejoicing includes not only inner approval and verbal admiration, but also corresponding behavior.
