What are the classics that the Buddha himself said? What are the more important ones?

The classic Buddhist monk, Da De, wrote the ~ Lun. The Buddha said the ~ Jing (including the past buddhas and the monks who became Buddhists in this world, such as the Six Ancestors), while the Buddha handed down the teachings in the next world, and the classic was also the ~ Jing, but there was a sentence at the beginning. So it can be easily distinguished. Buddha's teachings, all laws are unified, there is no difference between important and unimportant, there are 48 thousand methods to become a Buddha, only it is not suitable for you. Beginners don't look at the complete Shurangama Sutra, which is deeper. It is recommended to read the Diamond Sutra (the most widely circulated and far-reaching classic, which is a representative book of Buddhism), Heart Sutra (short and profound in meaning) and Amitabha Sutra (not too long, easy to understand and recite, which can best benefit all beings. )

It seems that Six Ancestors' Tanjing, Four Disciplines of Loving the Fan, and Guihai Cihang are also good. The comparison of textbooks is the Five Classics of Pure Land Sect:

The Sutra of Infinite Life of Buddhism

The Sutra of Infinite Life of Buddhism

amitabha sutra

The Lengyan Sutra.
