The Dharma taught by Shakyamuni Buddha is all empty. Why didn’t he say it directly?

Practicing Buddhism is always about opportunity. When Buddha taught Buddhism, he did not establish a sect, let alone write a book or biography.

The Buddhist scriptures we see now were summarized by later generations after the Buddha passed away, and then they were divided into various schools such as Mahayana and Hinayana Tibetan Buddhism

Mahayana Buddhism is divided into There are two sects. The Mahaprajna Sutra has more than 600 volumes. The Heart Sutra should be regarded as the outline and the Diamond Sutra is one of them.

I have not read the entire Mahaprajna Sutra, so I will not mislead you here. If you are interested, you can read it yourself.

The Buddha said that "empty" does not mean that there is nothing in it. It means that everything in the world arises immediately if it has a condition, and disappears if it has no condition. It has no self-initiation, so it is said to be empty.
