unconsciousness

n. condition of being unaware or unknowing; condition of being unconscious; state of having no consciousness (such as an object)

See also Unconscious mind. Unconsciousness, more appropriately referred to as loss of consciousness or lack of consciousness, is a dramatic alteration of mental state that involves complete or near-complete lack of responsiveness to people and other environmental stimuli. Being in a comatose state or coma is an illustration of unconsciousness. Fainting due to a drop in blood pressure and a decrease of the oxygen supply to the brain is an illustration of a temporary loss of consciousness. Loss of consciousness must not be confused with altered states of consciousness, such as delirium (when the person is confused and only partially responsive to the environment), normal sleep, hypnosis, and other altered states in which the person responds to stimuli.

Unconsciousness The universe being a vast aggregation of conscious beings, only the one source of all is unconscious, paramartha is described as absolute being and consciousness which are absolute non-being and unconsciousness from the human standpoint. Theosophy rejects the idea of anything being unconscious in the absolute sense, save on this plane of illusion. The Vedantic idea of an Unconscious behind all manifestation has reappeared in Occidental philosophy, notably in that of Eduard van Hartmann. Unconsciousness and consciousness are used in theosophy with direct reference to human understanding, so that what we call unconsciousness is merely consciousness on a plane so high, and with a range so vast, that human understanding cannot contain it; or that what we call consciousness would be unconsciousness to less evolved beings because these cannot contain or understand our consciousness. We may look upon spirit as being both conscious and unconscious: active spirit we would call the consciousness of spirit; but those incomprehensibly vast ranges of spirit beyond our power of understanding we would call inactive spirit, merely because we cannot comprehend it and therefore say it is relatively non-existent, although actually being the basis of all being.
Unconsciousness is often used in a relative sense, as for instance in speaking of the state of the first two and one half root-races as being one of mental torpor and unconsciousness, or in speaking of the three lower elemental kingdoms in comparison with the higher kingdoms. Also what is called unconsciousness may be only lack of power to register a memory, as in the case of a mesmerized subject on being aroused, or a person waking from sleep.
