In Hinduism scriptures reaching state of moksha salvation announces end of cosmic journey for soul atman within. Gaining moksha is the ultimate goal of life for all human beings on mother earth. None on mother earth can escape this destined and goal of life. However when to cover this journey, in present manifestation or the futures ones is purely up to us.
Moment an enlightened one left mortal frame it reaches state of moksha salvation, liberates forever from cycle of birth and death. This liberated soul atman finally enters kingdom of God (Vaikuntha in Hinduism), a point of no return. Vaikuntha in Hinduism is an imaginary place in cosmos where all souls’ atmans after liberation collected together.
Realization of God means reaching state of self realization; god realization, enlightenment!
We are primarily a spirit, a soul atman existing in heart. As a soul atman we manifest human body to work out our karma, remove dross impurities within. Indulging in Indian spirituality as detailed in Bhagavad Gita when human beings covered spiritual journey they slowly but affectively demolished their ego in totality. No sooner this happens; one can distinctly hear voice of Lord Krishna coming from within our heart.
Allegorically Lord Krishna is spirit, soul atman existing in our heart.
Guided by voice of Lord Krishna from within human beings can easily cover spiritual journey to reach state of enlightenment followed by moksha salvation. Demolition of ego is the biggest hurdle in spiritual journey. In present Kali Yuga the glitter of worldly riches stops human beings from indulging in spirituality to reach cosmic end of life. Only a seeker possessing willpower exhibited by Swami Vivekananda finally succeeds.
