Q: Isn’t Nirvana a fundamental spiritual experience?
Nirvana, as I know it, is an experience in which the separative personality is blotted out and one acts according to what is necessary to be done. It is only a passage for reaching a state in which the true individuality can be attained. That individuality is vast, infinite, and can contain the whole world within itself. It is not the small narrow limited individual self in Nature. When you attain that true individuality you can remain in the world and yet be above it. You can act and still be not bound by your action. For getting rid of the separative personality Nirvana is a powerful experience. After Nirvana you can go on to realise yourself as both the One in all and the One who is Many—and yet that One is also He.
