The nature of mind, just as the element of space, does not depend upon specific causes or conditions, nor does it depend on a gathering of these. It has neither arising, cessation, nor abiding. The clear and luminous nature of mind is as changeless as space. It is not afflicted by desire and other adventitious stains, which spring from wrong views and thoughts. It is not brought into existence by karma, and the afflicted emotions. Hence, it is also not consumed by the cruel fires of disease, aging, and death.
