Liberation. Enlightenment. Self-Realisation. Awakening. Samadhi. Nirvana. Moksha. Mukti.
They are all one in the same.
It is not some mystical concept. The goal is as real as you reading this. Achievable by anyone at any time. Just like laughing or crying, it is a experiential state that already exists insides you and is waiting to be unlocked. Once unlocked, you will experience your true nature. Like waking up from a dream, only this time you'll be waking up from a waking state.
No I, no you, no ego. No boundaries with the body and universe. No space. No time. Liberation from all bondages. This is the goal we are all striving for, unknowingly or knowingly.
