As per Lord Krishna in Bhagavad Gita all souls’ atmans manifested human form on mother earth to cleanse self of dross impurities within. This is the ultimate goal of life of all human beings on mother earth, to assist soul atman within in reaching cosmic end of life.
The goal of moksha does not belong to human beings, the mankind. The goal of moksha relates to spirit, consciousness existing in our heart as soul atman. It is this soul atman that desires regaining its lost original pure prime pristine primordial form at the earliest.
Indulging in spirituality when human beings finally succeed reaching state of self realization, god realization, enlightenment, it completes cycle for soul atman within. The pure soul atman finally liberates self from cycle of birth and death forever.
This liberated soul atman enters state of moksha salvation when an enlightened soul leaves mortal frame. The death of an enlightened one announces one reaching state of moksha salvation. The liberated soul atman finally enters kingdom of God (Vaikuntha in Hinduism).
We must never forget the entire cosmic journey belongs to soul atman, spirit within and never the manifest human form. Human life is but an interim stage for a soul atman within to cleanse itself of dross impurities within.
