Chapter 32 uses the metaphor of a tree to explain worldly existence. Can you describe this 'tree of worldly existence' based on the details provided?

Chapter 32 provides a detailed and philosophical description of the 'tree of worldly existence,' or samsara. According to the text, this tree is vast and perishable, with its roots above and its branches spreading immeasurably. It is born from the seed of the unmanifest, sprouting from ignorance, desire, and karma. Chapter 32 further elaborates that its leaves are desires and cravings, while its many branches represent the infinite beings with their different subtle bodies, all bound by karma. This tree, founded on body-consciousness and appearing pleasant from afar, is ultimately essenceless, like a plantain trunk, and filled with the thorns of sorrow, birth, and death.
