When someone takes undue advantage of us. People say ' pichchhale janam ka kuchchh lena dena hoga' There must be some dues from our past life. For centuries people have been fascinated by after life and before life. We also wonder what happens to us after death. I suppose the body disintegrates into five ingredients. ' chhiti, jal, pavak, gagan, sameera' ( earth, water, fire, space, and air). Now, what is this part of us which goes to space? probably that is what is called soul?
Meditation gives us a glimpse of death. It helps us understand what it is like on the other side.
