It's not a mystery. You are living in a miraculous era of God. This is a temporary miracle. The evil spirits have diverted the minds of the people towards a harmful subject which is completely nothing. But you can get the knowledge how spirits play their part in a human life.
Life is realizing your presence in some form on this earth. Life is to live. Wherever you go and whatever you read, at last you will come to a mere conclusion that life is to live, just to live. First of all you must know what a human being is. Human beings are just robots made of flesh and bones and toys of the spirits for their games. The soft-wares for these robots are spirits or invisible elements. These robots are programmed by different people by oral talks, writings and actions too. During this process the spirits possess a human being according to the programs. Further these robots can program themselves when they wish. Whatever it is they are all just spirits. A human being during his/her lifetime is living with many spirits which have joined one by one since birth. They are knowledge, skills, feelings, emotions, interests and everything. Even thoughts are not these robots' own. One after another they think and these robots either choose or reject the ideas which they transmit to their minds through brains in the form of thoughts. Brain is a media to connect the spirits to your mind. Your mind is just a computer's mind. After the destruction of a computer completely you will not get it's mind. The same is the case with the human beings. A soul is nothing but an energy needed for the functionality of a body. It is not a spirit or anything else. A human being doesn't have a spiritual body. Memories are different spirits. Spirits determine the destiny of a human being from his/her daily activities, talks and thoughts too. On death these spirits leave the body and go to different places. No one lives in any form after death.
