YUSEF:

We speak now of Soul.  Beyond the senses and what you might consider to be “reality” is the true reality, the true life.  The Soul IS.  Out of the Soul the personality manifested on this Earth comes.  The Soul allows the personality in order to face the challenges [of] this lifetime, and indeed all lifetimes.

The Soul, then, is that which is in communication with the human nature, [and] is actually a part of a larger, more complete, and “farther away” Soul entity.  The larger Soul continues in the presence of God, never separated even for a moment. [It is] the life-sustaining entity through which flows all knowledge.  It holds the memory and understanding and knowledge gained through all experiences and is a part of God. 

As Teilhard de Chardin says, We are not human beings having a spiritual experience; we are spiritual beings having a human experience.
