The suggestion of Mr. Bousfield is of value if only for its recognition of the limiting character of the neurological theories and physiological explanations and because it goes deeper and appears to suggest the theory which Aurobindo hints, namely, the existence of an overlapping psychonic brain functioning in all psychic processes, and effecting all changes in the physical through the vibration of ether that whilst separating them yet links them. We have the Sandilya Upanishad telling us that the prana extends twelve digits above the head which seems to be echoed by the theory of Bousfield who says that ether envelops both the psychonic and the physical brains.
The theory of the Upanishads also deals with the problem of spandana (throbbing) of vayu as the media of movement of chitta and Manas. All associative virility issues out of the throbbing movement of Vayu or akasa. The linga-sarira itself is a product of Akasa and Vayu in one sense. Mind, meaning Manas in Bousfield's theory, is called the Mnema of all impressions and is memory.* It is a manufacturer of psycho-grams; that is, it carries the impressions and congeals them into a set, unbreakable but powerfully influencing the entire mental processes.
Dr. Mc Dougall in his 'Mind and Body' says "the fusion of effects of simultaneous sensory stimuli to a unitary resultant is not a physiological or physical fusion or composition; but a purely psychical fusion; the unitary result exists only in the psychic sphere." He adds, "The materialistic assumption," that the structure of the mind may be fully described in terms of cerebral structure is untenable." There exists in the brain no such psychical medium of composition and the processes of the several sensory nerves simultaneously excited do not affect any common material medium to produce in it a complex physical resultant." It is meaning that is the cause of neural activity and there exists 'no such' unitary neural process correlated with 'meaning'. All response in fact is really in relation to meaning or significance. Thus there is needed this psychonic system, a system which has place for meaning and is able to correlate its activities with the physical neural system and influence all its motor expressions.
*Bousfield also affirms that there is no such thing as Unconscious mind, for all storage of impressions ideas etc. which are nascent are unconscious
