Many people believe in the concept of the soul.
The soul is seen as the incorporeal and immortal essence of a living being. Death is considered a separation of body and soul. Numerous myths and religious dogmas make statements about the fate of the soul after the death of the body.

Each soul is seen as an individual, unique phenomenon – something that represents the personality of a being.
In daily life each person permanently leaves impressions through interactions with others. It can be the sound of a voice, a smell,  a favorite dish, a political opinion, a habit and so on. If you were able to collect all these impressions (or informations) and put them together in an appropriate way, you would get a very good representation of that very person.
Something like that for example can happen at a funeral. Friends and relatives share their memories and anecdotes. When we hear this and remember, we feel the deceased is somehow still present – his soul is with us.
So, in a broader sense the soul can be seen as the sum of coherent information related to an individual.

What do I want for my soul? What is important for my soul?

Everybody wishes her/his soul to be immaculate and unscathed. It should protected from misuse and live forever.
Many people believe that confession is good for the soul and that it is prerequisite for forgiveness.
In former times the sale of indulgences was considered an appropriate way to reduce the amount of punishment the soul has to undergo.

Where is the soul located?
There are many philosophical, theological, and scientific ideas regarding the nature and location of the soul

For example the ancient Egyptians believed that the soul can be  found in the heart.
Drawings  from around 2000 BC show the god Anubis weighing the heart against the Feather of Maat (truth).
