There's a metaphor about a tree in Chapter 32. Can you explain what that tree represents?

The metaphor of the tree in Chapter 32 is used to describe the nature of worldly existence, or 'samsara'. The text explains that this 'tree of worldly existence' is vast and extensive, with its roots growing above and its branches spreading immeasurably. This tree is characterized as being filled with birth, death, and sorrow. According to Chapter 32, everything seen within this worldly existence is perishable, subject to being cut down and destroyed, which is why the comparison to a tree is made. The chapter further elaborates that while this tree might appear pleasant from a distance, if one tries to embrace it, its thorns will pierce the whole body, symbolizing the inherent suffering in worldly attachments.
