In advaita vedanta, they describe the body as being composed of 5 koshas :- Annamaya, Pranamaya , Manomaya , vigyanamaya, and Anandamaya
There is another division into:- Sthula shareera, Sukshma shareera, and Kaarana Shreera
Here it seems sthula shareera is same as annamaya kosha, Sukshma shareera can be said to comprise of Pranamaya, Manomaya and Vigyanamaya koshas together.
But then is it right to also say that anandamaya kosha is same as kaarana shareera?
It seems confusing since anandamaya kosha is supposed to comprise of bliss. Whereas Kaarana shareera is the ignorance in deep sleep.
Although there is bliss in deep sleep as well but it seems bliss should be much more than that.
