Jai Sri Ganesha,
Deep sound sleep could be taken as Yog Mudra while superficial dream state is a gross truth of Maya to trap spirit for long,
In Yog Mudra Mystics enters in their own self by piercing the superficial dream state in search of self and cause that needs wakeful conscious truth to relate the subject,
Whereby metaphysics cease to exist there starts the journey of inherent self to reach realms within oneself,
And it needs to blessings of one's true preceptor, Refuge in lotus feet of holy saint act as must conductive to the chapter concerned,
Jai Mahadev
