Question : What is Self Realization.
We need to know the difference between small "i" and big "I". Small "i" is called ego self and Big "I" is called Real Self. You can call it Source, God, Atman or any other name.
Self Realization is finding Real "I". That is why it is called Real"I"zation. We live in a dream created by false "i". We feel that I am the body, I am the mind, I am so and so.
When we drop the small "i" we become one with the big "I". Discarding the ego self is called Self Realization.
