When we sleep we leave everything, all the things that is precious to us.we do all this to enjoy our sleep time.
Mother who always keep her newborn close to her also leave him every day for a good sleep.
So that clearly shows we all have ability to loose our identities and attachments but only during sleep , if we practice it during our waking time only for one hour also then you will see nothing in this world can ever spoil your bliss equanimity state whether in happy or sad situation.
You will be immune to this worldly changing dynamics and will be able to face every situation without emotional turmoil.
