Conclusion
Swami Vivekananda’s well-known words aptly sum up the difficult  but not impossible journey from the state of “MIND” to the state of “NO MIND”,  from here to eternity, as beautifully painted by Shankara in his Nirvana Shatakam  and as  thoroughly examined by Patanjali  in his Yoga Aphorisms: ‘Each soul is potentially divine. The goal is to manifest  this divinity within by controlling nature - external and internal.’

When the vision of a person has gone beyond the  body-mind-intellect complex, when his internal and external nature has been  controlled, where is the question of the problems of duality like husband and  wife, parents and children, holy and unholy, likes and dislikes, attraction and  repulsion, day and night, success and failure, praise and reprimand, and so on  arising in him? He becomes Bliss personified. He enters the spiritual kingdom,  NIRVANA, KAIVALYA – a realm of ‘Sat chit ananda’.  Those who reach that state are called Isvara;  they do not remain human, they become divine – from BEING to BECOMING.
