Sleep vs Samadhi

In Viveka Choodamani verse 408,  Bhagwan Adi Shankara talks about the root of the universe being the mind and dissolving the mind is the only option to avoid the pluralism of outside world.  Sw. Chinmayananda wonderfully explains it as below  

"The mind turned outwards and gushing out is chitta. The manifestation of the world is from chitta only. If you want pure bliss and beatitude of Brahman,  you have to end this world. In order to do so,  quieten the mind in the contemplation of the supreme self which is your inner most core. Sit down and consciously withdraw your mind as though in sleep and experience that stage where there is no object , emotion or thoughts.   That conscious sleep is called Samadhi.   

In real sleep, there is no perception of the outer world, and hence no mis-apprehension, there is nevertheless a binding non-apprehension.  When you consciously sleep, there is no bon-apprehension either , only a complete apprehension of Reality.     

Wow.  Excellent analysis from Gurudev.

Hari Om.
