The word Spirituality itself defines all. As per Spirituality detailed in Bhagavad Gita we are primarily a spirit, a spiritual traveler on its cosmic life cycle of 8.4 million manifestations. On the earthly plane we all have independent identities related to our parents. Same is the case in spiritual world. Only when we indulged in spirituality did we realize we were an independent spirit, consciousness.
Every single spirit, the consciousness existing in our heart was independent of each other. As all 1000 pieces in a large puzzle were never identical yet combined together to form one large puzzle, all souls atmans in their cosmic sojourn also had an independent identity and combined together the power of all souls’ atmans in their pure form is what we called God Almighty.
Every human being our identity keeps on changing body after body, manifestation after manifestation. As the present human form is manifested by soul atman within to cleanse self of dross impurities within, it keeps changing form after another until it reaches state of absolute purity. The soul atman, the spirit remaining the same only the outer garb keeps changing.
The true identity rests with the actual master and controller of human life, the spirit existing in our heart. When indulging in spirituality detailed in Bhagavad Gita human beings finally succeed reaching state of enlightenment, stage of self realization, god realization the cosmic journey of life for soul atman, the consciousness within finally ends.
The pure soul atman, the independent piece of puzzle finally joins the complete puzzle, God Almighty himself, Brahman in Hinduism. This pure soul atman having gained absolute purity, in absence of dross impurities within need not manifest a human body again. The liberated soul atman finally enters kingdom of God (Vaikuntha in Hinduism).
Moksha salvation is the stage reached by an enlightened one when one leaves mortal frame.
