How does Chapter 32 use the metaphor of a tree to describe worldly existence?

In Chapter 32, the 'tree of worldly existence' is described as a vast and perishable entity with its roots above and branches spreading immeasurably. It is said to be born from the seed of the unmanifest, sprouting from ignorance, desire, and karma. The chapter explains that its leaves are desires and cravings, while its many branches represent the infinite beings bound by karma. This tree is characterized as being essenceless like a plantain trunk and deceptive like a mirage. Though it may appear pleasant from a distance, it is fundamentally harmful and pierces the body with thorns when embraced, symbolizing the suffering inherent in worldly life.
