The scriptures that Sakyamuni preached to the Lonely Garden in Jetavana for the Lonely Garden for Venerable Subhuti are a very important scripture. There are four scriptures, which can be called the classics among the scriptures. The more you read them, the easier it is to enlighten people.
First sentence: Tathagata has no origin or goes, so it is called Tathagata .
Tathagata has never been there, nor has it been, so it is called Tathagata. Just like he has been there, it seems that he has been there. In fact, he has never been there because he has been there and he has never left.
Tathagata is like his own nature. It is originally pure, and it is neither born nor destroyed. Because it is not born, it is not destroyed, and because it is not coming, it is not gone.

Second sentence: If you see me with your appearance and seek me with your voice, you will be a person who walks the evil path and cannot see the Tathagata.
Tathagata cannot be seen with eyes or sound. If it does that, it is wrong and cannot see Tathagata. The Tathagata here is not the Tathagata in the novel Journey to the West, but refers to the original appearance of all things, that is, the true essence of all things. How can we see this reality? Please read the next sentence.
The third sentence: All appearances are false. If you see all appearances but not appearances, you will see the Tathagata.
Shakyamuni tells us that all appearances in the world are false and unreal, that is, all the things we see, some feelings we have already felt, and even everything we think of, are illusory and unreal, and do not really exist.
Because everything is a name, for example: There is a book in front of you, and you seem to be real. If you analyze it carefully, you can't find a book at all.

I want to ask you where is a book? How do you answer? Is the text on the book representing it as a book, or does the cover or paper representing it as a book? Where does the text in the book come from? Where does the paper come from? The predecessor of Yibi Paper may be a tree, and the predecessor of Yibi Tree may be a flower or a seed. If you look for the root of this, you will find that this book is just a phenomenon of the harmony of cause and condition, and there is no real existence, nor a root to be found.
If you can see the origin behind things, that is, the truth behind illusions, you can see the Tathagata and the original face of things.
The fourth sentence: All the teachings spoken by Tathagata are not desirable, cannot be said, illegal, and illegal.

The Dharma spoken by Tathagata is actually false and unreal, and it is also a phenomenon of the combination of causes and conditions. In the book mentioned above, because the truth cannot be expressed in words and words, the Dharma spoken by Tathagata is to guide us to discover the truth, not the Tathagata's statement has been expressed.
The truth is actually indescribable. We should not be attached to the surface of words, nor do we obsess with book knowledge. These things are just tools. We should learn to use tools to achieve our true goals.
For example, our purpose is to cross the river, and what the Tathagata said is a ship. We must learn to cross the river by taking this ship, but we cannot stick to tools. Don’t regard getting on the ship as your purpose. Once you cross the river, you must throw away the tools.
