Chapter 15: Purushottama Yoga
the supreme person
The chapter opens with a striking image: a tree with its roots above and its branches below, whose leaves are the sacred hymns. Krishna says this tree of worldly life must be cut with the strong axe of detachment. He then speaks of the highest person, beyond both the perishable and the imperishable, and how knowing this frees a person from confusion.
Detachment is not coldness. It is what lets you leave the tangle without being ruled by it.
