Are there any Buddhist scriptures with profound philosophy? Who can recommend some books?

Many of these books are popular textbooks of Buddhist scriptures. For example, there is a book called Buddhist Stories.

Authors: Pan, editor in chief.

Publishing House: Tianjin Ancient Books Publishing House

In fact, these books are stories derived from Buddhist scriptures and translated into vernacular. More importantly, the author added a lot of subjective assumptions when extending the story. Therefore, if your level of Buddhism reaches a certain level, I suggest you dabble in the literal translation books of classic Buddhism, such as Guanyin Sutra, Six Ancestors Tanjing, Jinguangming Sutra, Amitabha Sutra, Miaofalianhua Sutra, Diamond Sutra, Dragon Tree Heart Sutra, Sutra and so on. There are still many Buddhist scriptures, but they are basically classic and ordinary. Let me recommend them here.
