There are far more wonders to perceive through this inward exploration than you can possibly believe until you begin such a journey for yourself. You are a soul; you are a particular manifestation of a soul, and it is sheer nonsense to think that you must remain ignorant of the nature of your own being. You may not be able to put your knowledge clearly into words, but this will in no way negate the value or the validity of the experience that will be yours once you begin to look inward.
Now you may call this a spiritual or psychological or psychic exploration, as you prefer. You will not be trying to find your soul. In that respect there is nothing to find. It is not lost, and you are not lost. The words you use may make no difference, but your intent does indeed.
