Master, may I ask whether during deep meditative concentration (such as for a fixed number of days) the manas (意根) can leave the body?
The manas follows the Tathāgatagarbha (如来藏) through past and present worlds across the ten directions; it can go anywhere, only the conscious mind is unaware of it. The accomplishment of the mind-made body (意生身) also lies within the manas.
