Unity Consciousness or Samyak-prajnya.

There is one supreme consciousness that governs the universe. Only the human beings can try to attain to this highest level of consciousness with the help of yoga, taking recourse to dhyana, dharana, tapas and samadhi or by activating kundalini shakti with the help of a good expert in hathayoga. Otherwise, it is just a dream. However, there is still hope. When a person lives a very simple life, cleansed of all blemishes acquired since birth such as desires, aspirations, attachments, anger, selfishness, jealous, ego, etc. there is scope for attaining to higher level of consciousness. 

   By the way, this supreme consciousness or samyak-prajnya (unity/oneness/absence of duality) is also called "Shree Krishna-prajnya".   One prince Gautama left his palace, even deserted his wife and child and wandered in the forests for almost seventeen years and reached the state of 'nirvana' and came to be called 'the Buddha'. The Buddha is the highest level of consciousness where buddhi is devoid of dualities and it is not the name of a person, and as such, anybody can reach that state!

   At this height of consciousness, the person is calm, quiet, unperturbed  of the happenings; he is not in any way concerned and is called a 'sthitaprajnya' in the Gita. Anybody, who keeps quiet, resting in peace with his Self, established in his Self becomes a sthitaprajnya. However, this state of solitude, mind-less or quietude should not be for only short time like a few minutes or days or months as in chaturmasya. It should be final state like Gautama sitting in nirvana forever! 

  Mind is energy and it is vibrant causing disequilibrium, restlessness and engages the jiva in all sorts of positive and negative thoughts, aspirations, dreams and prods it to resolve and act and thereby destroys its true nature of sat-chit-ananda. It creates illusions and make-believe worlds of joy that are short-lived and leads ti total disillusionment at the end. Unless  this mind is killed by higher knowledge para vidya or jnyan the jiva cannot escape the cycle of rebirths.
