It is still among the unknown issues. Whether there is life after death is still a matter of debate among some people. However, according to the Jewish religion, death is not the end of life. The world we live in is like a corridor that takes us to another world. Believing in the other life, the world to come (olam haba), where people will be judged and their souls will be revived, exists in Jewish thought and philosophy. Every Jew has a share in the world to come. (Mishna sanhedrin 11:1)
For the sake of the sanctity of life, every Jew must faithfully perform all his mitzvot. While performing every mitzvah, "God" should be remembered and performed for Him. Because it is what gives us life.
Religious laws and practices regarding death and mourning are based on two principles. To honor and respect human beings, even if they have lost their lives (Kibud Ha-met), to comfort those who are in mourning mentally, emotionally and spiritually and to ensure their well-being (Nichum Avelim). The Jewish tradition is based on relieving the pain of mourners by maintaining respect for the dead.
