Human beings are not eternal, and no matter how long their life is and how healthy they are, everybody knows that death awaits them at the end. Some people die accidentally due to the sad coincidence of events; others leave life according to their own will. Death occurs to all people without exception at the end of their lives. No matter how it happens, it is a subject of intense discussions and even experiments because all people are afraid, fascinated, and intrigued by what awaits them after their physical body stops functioning. The main question that is left without an answer, but represents utmost importance for the whole of humankind is whether there is a spiritual world that awaits people after death, and if it really exists, what it represents. The spiritual world for people means the immortality of their souls, which is in general highly important from the point of view of religion and philosophy. Christianity and Islam pose much attention to the modest, humble, and correct life of believers who want to be gratified for their goodness in the afterlife. There are a number of sins that are punished by eternal sufferings for the soul that are called to engage people in virtuous lives in the hope for a happy afterlife. However, no matter whether hell or heaven expects their souls, it is clear that the immortal soul exists and proceeds from one world of earthly human beings to the eternal spiritual world. Other religions such as Buddhism deny the fact of the soul’s existence and state that human life exists only due to the flow of super-powers and super-energies in the world. My personal opinion on the issue is heavily influenced by the religion I have because all followers of Christianity are taught from a young age to believe in the immortality of human souls to make people responsible for the outcomes of their lives. People should live carefully, without sinning and committing atrocities towards other people or nature in order to be rewarded for this later. I believe that there is something beyond the world in which humankind lives because of many stories about mysterious forces that guide people, give them extraordinary possibilities, and bring sacred knowledge to the human world. I am sure that the soul of each person is transformed after his or her death and passed on to another creature, not sure the human being but an animal or a plant. It is impossible to get the whole cultural, spiritual and intellectual knowledge passed on from century to century by our ancestors; it would take much longer for people to grasp all basics of life in case they did not have the subconscious memory of their souls. Besides, I believe in the existence of an immortal human soul because I am sure that only education and upbringing cannot produce great people or criminals; there is something beyond their social and genetic background that makes them commit the greatest good and the greatest evil in their life. One life would be not enough to raise such people as Hitler or Gandhi. For this reason, I am sure that our soul is much wiser than we are, showing us the way through life by symbols, hidden signs, and hints that we rarely understand but the presence of which we certainly feel. The immortal soul is something for the sake of which people
