It is believed in any religion that soul is the real being of human. When death get control over body, the soul still living in outer dimensional worlds or somewhere (what religion that is). Without any religion person is said to be ateist, and usually dont believe that here is soul. Without soul, here is no thing named life purpose, if you start to think. Material world is just like the wheel, when things end then some things begin...you know what i mean.
What is soul?
What you think? So what is soul? Are ghosts pure souls? My answer to that question is nope. Living guy is made for 3 things: 1. Physical body and brain/psyche (this is what science can tell) 2. Energybody (like the physical one, but in unknown levels of energy and this is the point whitch seating physical body and the soul together) 3. The soul (pure bliss, joy, light, love, wisdom, courage. 1 soul is like allpowerful cosmic God being, what is connected to everything, cause it is not to sealed to particular place or time).
So ghost is made for latest 2 things. Ghosts have ego too like living persons, but your pure essence is without it. Ego is only an illusion like everything in these things 1 and 2, so only real thing what is not illusion is soul, and there is reality named Heaven, Tuonela etc. Everything else is only ilusion what is made by ego, what is illusion itself.
If you can remember some situation, when you has felt inner peace for non-being/life itself, example this feeling comes from your soul. Without ego you will feel inner peace all the time, and you never feel any experience for physical, emotional and mental pain anymore. Like Buddha is said, every misery is made by ego. So is our goal to kill or vanish ego? No! Ego hold our soul here and through ego we can live. When die, you born again, but if not, you start to live without ego in reality (you never come back to this illusionary world again) and its good to remeber that soul cant die or vanish like physical body.
Psychic abilities dont exactly come from your soul, but the life goal is to make sense of ego vanish (not ego itself), and cause your ego cant get control over yourself, you can control your subconscious mind and there all your paranormal skills lie dormant. Only some skills are like outer science laws, but everything else is found by science. These abilities are example levitation and time traveling. These abilities are used controlling your energy system, not exactly unconscious. And its good to again say something to you, so keep your mind, that these skills not come from your soul, its all made by ego. So how to get control over your ego? Meditation is usually good to that, but normal meditation is not so effective. Like i has wrote i suggest you to check nadis, chakras and then Kundalini yoga. You would to find your true nature beyond limits of ego.
