Consciousness will always be present, though a particular consciousness may cease. For example, the particular tactile consciousness that is present within this human body will cease when the body comes to an end. Likewise, consciousnesses that are influenced by ignorance, by anger or by attachment, these too will cease. But the basic, ultimate, innermost subtle consciousness will always remain. It has no beginning, and it will have not end.
