The soul after it leaves the body travels through several states or planes until the psychic being has shed its temporary sheaths, then it reaches the psychic world where it rests in a kind of sleep till it is ready for reincarnation. What it keeps with it of the human experience in the end is only the essence of all that it has gone through, what it can use for its development. This is the general rule, but it does not apply to exceptional cases or to very developed beings who have achieved a greater consciousness than the ordinary human level.
When the body is dissolved, the vital goes into the vital plane and remains there for a time, but after a time the vital sheath disappears. The last to dissolve is the mental sheath. Finally the soul or psychic being retires into the psychic world to rest there till a new birth is close.
The departed soul retains the memory of its past experiences only in their essence, not in their form of detail. It is only if the soul brings back some past personality or personalities as part of its present manifestation that it is likely to remember the details of the past life. Otherwise, it is only by Yogadrishti that the memory comes.
Our life' repose is in the Infinite:
It cannot end, its end is Life supreme.
Death is a passage, not a goal of our walk:
Some ancient deep impulsion labours on:
Our souls are dragged as with a hidden leash,
Carried from birth to birth, from world to world,
Our acts prolong after the body's fall
The old perpetual journey without pause.
