Changes

A: Not in the physical heart, not in the organ. It is in a fourth dimension, an inner dimension. But it is in that region, the region somewhat behind the solar plexus, it is there that one finds it most easily. The psychic being is in the fourth dimension as related to our physical being. <ref>http://incarnateword.in/cwm/06/3-november-1954#p22</ref>

The place of the psychic is deep within the heart,—but deep within, not on the surface where the ordinary emotions are. But it can come forward and occupy the surface as well as be within,—then the emotions themselves become no longer vital things, but psychic emotions and feelings. The psychic so standing in front can also extend its influence everywhere, to the mind for instance so as to transform its ideas or to the body so as to transform its habits and its reactions. <ref>http://incarnateword.in/cwsa/30/the-psychic-being-and-its-role-in-sadhana</ref>

The psychic being is in the heart centre in the middle of the chest (not in the physical heart, for all the centres are in the middle of the body), but it is deep behind. When one is going away from the vital into the psychic, it is felt as if one is going deep deep down till one reaches that central place of the psychic. The surface of the heart centre is the place of the emotional being; from there one goes deep to find the psychic. The more one goes, the more intense becomes the psychic happiness which you describe. <ref>http://incarnateword.in/cwsa/30/the-psychic-being-and-its-role-in-sadhana</ref>

...it is described in the Upanishad as no bigger than a man's thumb, it can by the spiritual influx enlarge itself and embrace the whole world with the heart and mind in an intimate communion or oneness. Or it may become aware of its eternal Companion and elect to live forever in His presence, in an imperishable union and oneness as the eternal lover with the eternal Beloved, which of all spiritual experiences is the most intense in beauty and rapture. All these are great and splendid achievements of our spiritual self-finding, but they are not necessarily the last end and entire consummation; more is possible. <ref>http://incarnateword.in/cwsa/21/the-double-soul-in-man#p13</ref>

It [a flame in the heart as big as a man's thumb] is the psychic fire kindled in the heart. The psychic being in the heart is described by the Upanishads as of the size of a thumb, ''aṅguṣṭha-mātraḥ puruṣo'ntarātmā''—it may manifest first as this psychic flame. <ref>http://incarnateword.in/cwsa/30/experiences-associated-with-the-psychic#p10</ref>

There is a psychic world—a sort of Heaven of peace and beauty and harmony. It is also a place of rest for the soul between two incarnations in which it absorbs its past experiences and becomes ready for another birth. <ref>http://incarnateword.in/cwsa/28/the-psychic-being#p100</ref>
