It is not a memory of the past in the sense of the horizontal line: today, yesterday, the day before, etc, but rather in the sense of the vertical line: here, higher, still higher, etc. It is a “memory” which does not link the present to the past on the plane of physical, psychic and intellectual life, but which links the plane of ordinary consciousness to planes or states of consciousness higher than ordinary consciousness.
It is the faculty of the “lower self” to reproduce the experience and knowledge of the “higher self” or, if you like, the faculty of the “higher self” to imprint its experience and knowledge upon the consciousenss of the “lower self”. It is the link between the “higher eye” and the “lower eye”, which renders us authentically religious and wise, and immune to the assaults of sceptism, materialism and determinism.
It is this also which is the source of certainty not only of God and the spiritual world with its hierarchical entities but also of the immortality of our being and reincarnation, wherever it is a matter of reincarnation. “Dawn is the friend of the muses” and similar popular proverbs, such as “the morning hour has gold in its mouth” or “morning is wiser than the evening”, relate to the benefits of vertical memory from which one benefits in the morning, after the return of consciousness from the plane of “natural ecstasy” or sleep.
