In this chapter entitled Vibhuti Yoga Arjuna asks Krsna to help him see God’s immanence in the world so that he may remain focussed on the Divine even while he is living in the world.
Krsna begins by saying that He is the core of all beings. He then enumerates some of the manifestations of Brahman, highlighting the best in each category. This enables even the least developed to get inspired. As one grows spiritually one sees Divinity even in ordinary manifestations. At the highest level one is rooted in Brahman and does not need any manifestation as a reminder of the Divine.
Krsna ends by saying that the entire universe is only a minuscule, insignificant part of the limitless expanse of Brahman. That Brahman you are. Rise above the universe and understand your sublime Grandeur.
