My Understanding : We see many different lamps, but the fire in each is the same, indivisible. Similarly, we observe various living beings, but they are all manifestations of Brahman. Our ignorance veils the truth, leading us to perceive them as separate. In reality, He resides in the heart of every being. Everything else in this world is material, transient, and temporary.
