<div span style="background-color:transparent;color:#000000;">Chitta, the basic consciousness, is largely subconscient; it has, open and hidden, two kinds of action, one passive or receptive, the other active or reactive and formative. As a passive power it receives all impacts, even those of which the mind is unaware or to which it is inattentive, and it stores them in an immense reserve of passive subconscient memory on which the mind as an active memory can draw.But ordinarily the mind draws only what it had observed and understood at the time,—more easily what it had observed well and understood carefully, less easily what it had observed carelessly or ill understood; at the same time there is a power in consciousness to send up to the active mind for use what that mind had not at all observed or attended to or even consciously experienced. This power only acts observably in abnormal conditions, when some part of the subconscious chitta comes as it were to the surface or when the subliminal being in us appears on the threshold and for a time plays some part in the outer chamber of mentality where the direct intercourse and commerce with the external world takes place and our inner dealings with ourselves develop on the surface.</div><span style="background-color:transparent;color:#0066cc;"><u><ref>http://incarnateword.in/cwsa/24/the-instruments-of-the-spirit#p6</ref></u></span>
