The doors of God Almighty are open to one and all in equal measure. One may belong to any religion, faith or belief still, one can follow spirituality detailed in Bhagavad Gita to reach God in their lifetime. Reaching state of moksha salvation means reaching kingdom of God (Vaikuntha in Hinduism). The state of moksha salvation is reached when a soul atman gains absolute purity.
Liberation from cycle of birth and death is what moksha salvation all about. The moment an enlightened one leaves mortal frame one reaches state of moksha salvation.
Any human being on mother earth, one from masses commoners can indulge in spirituality as detailed in Bhagavad Gita. People world over must bear one thing in mind, state of enlightenment followed by moksha salvation can be reached only by indulgence in Bhagavad Gita. In present times one single scripture Bhagavad Gita suffices for entire mankind to reach god in their lifetime.
There was nothing more pure and sacrosanct than teachings of Lord Krishna in Bhagavad Gita.
As nothing in Bhagavad Gita can be understood literally one needs mastering art of contemplation (chintan) to reach the hidden underlying meaning.
The state of moksha salvation can never be reached indulging in religious practices (rituals) nor there was a shortcut method to reach God in one’s lifetime. One has to become a Swami Vivekananda in real life to practice spirituality as detailed in Bhagavad Gita. Only then one can hope reaching state of enlightenment followed by moksha salvation.
