Derived from the Sanskrit word: Sukha meaning ease and Mara meaning death

"The Spirit is neither born nor does it die at any time. It does not come into being, or cease to exist. It is unborn, eternal, permanent, and primeval. The Spirit is not destroyed when the body is destroyed... Just as a person puts on new garments after discarding the old ones; similarly, the living entity or the individual soul acquires new bodies after casting away the old bodies."
