Moksh Ki Prapti
The path is same as of redemption. A redeemed soul is a pure soul. Purity is the only condition for the differentiated particles of existence, consciousness, bliss (Sat Chit ananda) to reunite back or merge with it or undifferentiate.
Moksha is important because it ends the souls or conciousnesss suffering and pain.
Moksh is attainted when the individual becomes liberated from the cycle of birth and death and attains eventual union with the Supreme Being.
In a lifetime people build up karma, both good and bad, based on their actions within that lifetime. This karma affects their future lives and existences. People must take responsibility for their actions either within this life time or the next. Death is a key part of this cycle and is treated with specific importance. Death is the last samsara (cycle of life) referred to as the last sacrifice.
Moksh is the end of the death and rebirth cycle and is classed as the fourth and ultimate artha (goal). It is the transcendence of all arthas. It is achieved by overcoming ignorance and desires.
