Context: Water and a bubble on it are one and the same. The bubble has its birth in the water, floats on it, and is ultimately resolved into it. So also the Jivatman (individual soul) and the Paramatman (supreme soul) are one and the same, the difference between them being only one of degree. For, one is finite and limited while the other is infinite; one is dependent while the other is independent.
