Brahman (God Almighty) does not differentiate between human beings. In the eyes of God all were equal. Every single human being on mother earth had the right to seek God. None could stop one from reaching God. Lord Krishna in Bhagavad Gita clearly says, if we had the requisite willpower to negate karma to zero, overpowering five senses and mind forever then none in this world not even God Almighty would stop us from completing our cosmic journey.
We were born a human being to reach highest pedestal of cosmic life, stage of 8.4 millionth manifestation. Dwelling on path of spirituality all the time, unveiling hidden underlying messages in Bhagavad Gita we could easily cross ocean of Samsara (worldly life) to reach state of enlightenment. It never matters what we are. Our status, our affiliations are limited to earthly relationship having nothing to do with spirituality. In the domain of God every single individual human being has been given equal right. We only need becoming a Swami Vivekananda in real life. If we succeed gaining enlightenment moksha salvation would automatically follow.
When an enlightened one leaves mortal frame one reaches state of moksha salvation forever.
Spiritual wisdom was not propriety of limited few. Even the contents of Bhagavad Gita were not limited to Hinduism religion. Any human being world over belonging to any religion, faith or belief can ceremoniously indulge in teachings of Bhagavad Gita to gain enlightenment in present life time. The 700 shlokas verses contained in Bhagavad Gita were pure wisdom following which human beings successfully gained enlightenment followed by moksha salvation.
No earthly binding of any type could stop a seeker to realize god. People who committed crimes and are rotting in jails but feel repenting can also follow precepts of spirituality to gain enlightenment. We only need mastering delicate art of contemplation (chintan) to understand the gist of Bhagavad Gita. Literally we can never understand anything in Bhagavad Gita or Upanishads (independent spiritual treatises). We have to again and again indulge in self enquiry to seek answers to our queries within. As queries within dissolve we become wiser in the spiritual journey of life. Spiritual journey was all about removing dross impurities from our soul atman.
The teachings of Bhagavad Gita can be followed by any human being world over. There was never any restriction of any kind. The entire teachings of Bhagavad Gita in Sanskrit along with English transliteration, the gist of 700 shlokas verses is available for mere $1 from Gita press, Gorakhpur, India. Despite being a highly subsidized publication, none world over comes forward to indulge in path of spirituality that finally leads to state of enlightenment.
No matter how many times we read Bhagavad Gita literally, we understood nothing. Only by contemplating on spiritual disciplines contained in Bhagavad Gita we can reach the hidden underlying truth.
Sri Ramakrishna Paramhansa was an ordinary mortal and so was Maharshi Ramana. Yet both these seekers successfully engaged in spiritual doctrines to reach state of enlightenment and finally moksha salvation. If Sri Ramakrishna Paramhansa and Maharshi Ramana can successfully undertake the spiritual journey, so can others world over.
