Premanand Maharaj Ji
What does moksha actually mean, and how is it different from reaching heavenly worlds?
Moksha is freedom from birth and death
Reaching higher worlds like heaven means your downfall is stopped, but moksha means freedom from the cycle of birth and death. It is not wandering in any world; it is knowing in your own experience that you are not the body but of the nature of the Supreme.
Moksha means being free of the cycle of birth and death. It is not about wandering in some realm. Moksha is freedom from birth and death itself. Now there will be no more birth and death.
