Chapter XV

Krishna introduces the Aswattha (Banyan tree) as a sacred symbol whose inverted structure (roots above, branches below) represents the nature of worldly existence and whose leaves whisper truth.

Krishna elaborates how the tree's branches extending to heaven and earth parallel human deeds arising from qualities, and how the tree's sensory stimulation mirrors how human life quickens through sensory temptations.

Krishna explains how the tree's rootlets binding it to soil parallel how actions in the world bind humans through ever-tightening bonds of karma.

Krishna teaches that understanding the tree's teachings and meaning leads to wielding the axe of detachment to cleave the roots and transcend sense-life.

Krishna describes the higher realm where those who escape worldly attachment attain permanent existence without death or decay, identifying it with the Father and First Creator.

Krishna states that those who break free from passion and dreams, sever bodily constraints, and worship the Highest cease to be governed by worldly forces and achieve eternal passage.

Krishna describes the divine realm as having a unique sun, moon, and light different from earthly illumination, from which those who perceive it never return.

Krishna explains that the eternal Spirit emanates from him, takes form, and gathers the five senses and mind from Being's storehouse, much as wind gathers scents from flowers.

Krishna contrasts those who fail to perceive Spirit in its comings and goings with holy souls who, through striving and enlightenment, perceive the Spirit within themselves.

Krishna claims that all light (sun, moon, fire) emanates from him, and that he penetrates all matter—clay, plants, and living bodies—providing vital force and life.

Krishna teaches that existence consists of two modes: the Divided (all individual beings) and the Undivided (that which transcends individual manifestation).

Krishna identifies himself as the Purushottama (Supreme Person), the Highest Lord who transcends both divided and undivided being, sustains all worlds, and is worshipped as Life Supreme.

Krishna promises that whoever knows him with unclouded mind achieves wisdom, worships him wholly, and becomes free from worldly works in bliss.

Krishna declares the teaching as a sacred and secret mystery whose comprehension grants wisdom and liberation from karmic bondage.
