First of all, all the Buddhist scriptures were told by our teacher Sakyamuni Buddha, or relayed by the Buddha himself. Secondly, in the fourth article of Mahayana Buddhist Sutra, which is solemn, pure and equal, Buddha Sakyamuni told the story of the monk (he was called Amitabha Buddha after becoming a Buddha), and he said 280 words when he made a vow to become a Buddha. This poem was said by Amitabha himself and relayed by Sakyamuni Buddha. It is the method of becoming a Buddha and the heart sutra of Amitabha. The Buddhist Sutra of Amitabha is also the supreme bodhicitta of Buddhist monks (before Amitabha became a Buddha).

There are four most important words in Amitabha Heart Sutra:

Tathagata is subtle and strict, and there is nothing in the world (I have the wisdom and virtue of Tathagata)

May my Buddha's quiet voice and dharma sound be popularized without boundaries (this is the way for Amitabha to become a Buddha, and all the Buddhas in the three realms will only do one thing after showing their way, that is, "dharma sound is popularized without boundaries")

I hope that when you live in Samadhi, you will be radiant and shine on all things, so that you will be vast and clean, and you will be more solemn (this is the way for Buddha to become a Buddha, and Buddha is convenient for all beings)

Even if I no longer suffer, I hope my heart will never retreat. (extremely bodhi, don't look back. )
