When was the Buddhist scripture related to Amitabha said? What did you say later?

The Buddhist scriptures related to Amitabha started from three books of Pure Land, namely Amitabha Sutra, which was told to Silent Garden by the Buddha in Swat. There is also a translation of this Buddhist scripture, which was translated by Master Xuanzang in the Tang Dynasty, and it is called Praising the Pure Land Buddha. It is basically the same as the Amitabha Sutra, but Master Xuanzang's translation is more accurate.

There is also the Buddhist Sutra of Infinite Life, which was written by a noble scholar at that time. He imprisoned his parents. Wei Tixi hates the evil world and hopes to live in pure land. Buddha said it in the palace at that time.

The third book is the Buddha's Endless Life Sutra. The Buddha lived in the Wangshe Mountain and gave a lecture at that time.

Later, the Five Classics of Pure Land were added, such as "The Great Trend to Buddha's Mind" and "Bodhisattva's Wish". Another is the past life theory.

Therefore, the most important classic of Pure Land Sect is the Five Classics and One Theory. If you are interested, you can read the scriptures in official website, Torin Temple.
