In Chapter 10 of the Gita, God describes Himself to humankind. We have differing views about creation as well as about the existence and nature of a higher power. Some of us question the validity of any assumptions about these notions.
But Lord Krishna speaks in light of orthodox Hindu opinions. He answers doubts about what the Divinity represents by telling us He is the best of whatever the human mind can imagine.
God says He is the most powerful of weapons, the lion of beasts, the holy Ganges of rivers, the cleansing wind, life, death, and the future. He tells us that He is beyond time and He is time itself. He is both the cause and the source of everything. He explains that while no one understands His power, the wise know He causes and moves the world.
