Using the details from Chapter 32, describe the metaphor of the 'tree of worldly existence'.

Chapter 32 presents a detailed metaphor of worldly existence (samsara) as a vast tree with its roots above and its branches spreading immeasurably below. The chapter explains that this tree is born from the seed of the unmanifest, sprouting from ignorance, desire, and karma. It is described as being essenceless, like a plantain trunk or a mirage, and fundamentally perishable. According to the description in Chapter 32, its leaves are desires and cravings, and its branches are the infinite beings with their subtle bodies, all bound together by the bonds of karma and flourishing with attachments to relatives, wealth, and possessions.
