Chapter 32 talks about a 'tree of worldly existence'. What is this metaphor and what does it represent?

In Chapter 32, the text describes the 'tree of worldly existence' as a powerful metaphor for our material life. It is depicted as a vast, extensive tree with its roots above and its branches spreading immeasurably. This tree is filled with the cycle of birth, death, and sorrow, and everything visible within it is ultimately perishable. The chapter notes that it is called a 'tree' precisely because it is subject to being cut and destroyed. Though it might appear pleasant from a distance, when one tries to embrace it, its thorns pierce the whole body, symbolizing the inherent suffering and transient nature of worldly pursuits.
