Jai Sri Ganesha,
In deep sleep man recover from the delusion of dream world,
Deep sleep could be a posture of self with wakeful or conscious thread to reconnect self with, that free from dream world both ways,
Duality and doubts cease to exist and light eternal manifest to support self suitable, could be called a state of Samadhi,
In this state of self identity merged with truth and Sat alone remains active to pacify self and the cause,
Indeed a state which convince the truth and the cause at same plane, and paves the stage of pre-emancipation truth,
May Lord bless all,
Thanks please
