Chapter 32 of Sai Satcharitra mentions a 'tree of worldly existence'. What is that and how is it described?

In Chapter 32, the 'tree of worldly existence' is a powerful metaphor for samsara, or the cycle of life and death. The text explains that this tree has its roots above and its branches spread immeasurably, making its full extent difficult to comprehend. It is characterized as being filled with birth, death, and sorrow. The chapter notes that because this existence is subject to destruction, it is aptly called a tree. A poignant description in Chapter 32 warns that while this tree may appear pleasant from a distance, embracing it leads to pain, as if "thorns pierce the whole body," illustrating the ultimately sorrowful nature of worldly attachments.
