Next, you can see Han. After the cold, if you have already started practicing, you can read the Shurangama Sutra first. You should pay attention to all kinds of realms in the Shurangama Sutra. If not, you can look at Hua Yan first, because Fahua has fewer volumes: P
You can watch Pure Land III at any time, and you can finish it in half a day if you watch it carefully, but there is a profound meaning in Pure Land III, which is not as simple as it seems. If you want to practice the Pure Land Method, you should read other classics, and then come back and read Pure Land III carefully. You will have a deeper understanding and stronger confidence in the Pure Land Method.
This is the part you mentioned. As for the part of the classics you didn't mention: Buddhist Sutra, Eight Awakening Sutras and Forty-two Chapters Sutra, these three classics are all very short, but they need to be read. Vimalakīrti Jing, an important classic since childhood, can be seen in combination with Prajna Jing; The Great Nirvana Sutra, which has been published since then, has a great weight, which can be seen; Understand the profound and dense classics, this is a classic of epistemology. If you are interested in epistemology, you can read it, but the classics of epistemology are not easy to understand. The Shurangama Sutra was created by the founder of Dharma. Of course, it won't be too studious. You should also read the Jue Yuan Sutra.
Theoretical part: The Doctrine of the Mean is a must-see and a very important treatise. If someone says that he can understand the Prajna Sutra, but he can't understand what the Middle Way says, then that person is lying. Although this is the basic theory of epistemology, which must be learned, this theory is more than that. Maitreya explained in great detail the realm and methods of practice at different levels from ordinary people to saints. If you want to practice meditation, it's worth taking the time to study. The above two are the basic theories of Mahayana Kongzong and Youzong. Other recommendations (in no particular order, follow one's inclinations): Great Wisdom Theory, Six Ancestors' Tanjing, Four-line View of Bodhisattva's Patriarch, Ode to Bodhisattva's Patriarch, Zhao Theory, Mahayana Solemnity Theory, Outline of Teaching View, Disciples of Hundred Ways, and Master Hua.
If you want to go deep into a case, of course, there are many related Confucian classics, but if you understand all these, the foundation of Buddhism will be quite deep.
