There are many conceptualizations of the Soul. Just take a look in your dictionary! Many interpretations, and some of them contradict each other.
Some people consider the soul the same as the higher self... it is not. In my experience, the soul is a tiny spark of brilliant light, the seed of your consciousness. It looks like a star... the ancient Egyptians believed that every star in the heavens represented a human soul.
The soul is in unity with the Divine, and cannot be harmed by any of your actions in this lifetime... Religions who refer to sin as a "stain on the soul", are actually referring to the higher self. You cannot harm your soul any more than you can harm God-dess.
...But! If your body gets too plugged up with stress and karma, it becomes no longer a temple of the soul, and your soul may leave the body. Then we do what is called a "Soul retrieval" to bring it back. There is an expression, we sometimes say someone has no soul... they have one, but it may have fled! They are not able to feel it anymore, so it no longer is guiding their actions and choices. They have gone too far off their Dharma, their path.
For what shall it profit a man, if he shall gain the whole world, and lose his own soul?
Sometimes under severe trauma, like a car accident people experience altered perceptions... time seems to slow, small details get magnified, sometimes they are not aware of sound, or notice that the sound they hear, is themselves screaming... or theu may see themselves as if from above, or outside.
This is called clinical detachment... It is a Divine mercy, that the soul often gets removed from the body before death or accidents. Sometimes people die of shock... when the soul is out of the body for too long, sometimes the body thinks it's work is done, and starts to shut itself down, to return to dust. This is a spiritual perspective, medical explanations may differ.
Children are sometimes much more aware of thier souls, than adults are. They may experience the soul leaving the body when it is stressed. Sometimes I have gone looking for the soul in someone, doing a soul retieval, and found what looks like a steel ping pong ball! The soul, is inside. As a child, not understanding that their soul cannot be harmed, they armoured it... like locking their greatest treasure in a bank vault. It is perfectly safe, in the ball or out of it, but the effect of the ball was that they could no longer feel thier soul or feel its guidance, or its love and joy. Symbolically, the soul sometimes apears as thier tiny baby selves. Innocent, pure, loving and joyous.
The soul meditation is good for people who are too detached, and have a hard time staying in their body and connecting with it. Do it as often as you please. The more you do it, the more you will become aware of your own soul as a guiding principle in your life. Your soul knows why you chose to incarnate, and what you truly are... Usually if will not speak in words, except via the Heart Voice, but it communicates!
