Can one who has entered the fifth body no longer obtain a gross physical body after death?

According to Osho, entering the fifth body does not bar future physical rebirth. Reincarnation depends on vasana—residual or consciously adopted intention. A liberated being, like a Tirthankara, may deliberately bind a vasana to assume a gross body again for the dharma of guiding others. Thus return is possible, chosen through purpose, not forced by ignorance.
