However death is defined as the end of the time spent by a soul in one species and birth is defined as soul entering in another species. The ones, who do not meditate on God, will never be able to attain salvation and continue to live in the cycle of birth and death. “The ignorant and oblivious do not serve the true Guru, how will they find salvation? They die only to be reborn over and over again. They continue to be struck down at the door of death” (Guru Granth Sahib Ji, 115).
How do we know we are reborn? We take birth and we do die. Sikhism does believe in the existence of heaven and hell, however, heaven and hell are created to reward and punish, one will then take birth again until one merges in God. According to some religion, the soul either goes to heaven or hell after death and stays there. So, how are people and other animals being born on this Earth? Is God creating new souls? If He is then no matter how big is heaven or hell it is going to be filled. If you consider a lake as heaven and think of drops of water being added to it as souls, then no matter how big the lake is, if no drops of water is leaving the lake, it is going to be filled some time in future. Our souls just ending in heaven or hell after death and God creating new soul doesn’t make sense.
What happens after death? Two things can happen after death. First, if you meditate on God and purify your soul by getting rid lust, anger, greed, attachment, and ego, you merge back with God and your cycle of life and death is gone forever. The other one is that if you do not worship God and realize Him, you will be reincarnated. If you were on the right path to God but did not purify your soul within the lifetime you had on the Earth, you will be given more chances in human form to become closer and closer to God. If you have not made any effort to love God and purify your soul, you will end up wandering through the 8.4 million species.
“When the body is filled with ego and selfishness, the cycle of birth and death does not end” (Guru Granth Sahib Ji, 126). “As long as the tongue does not chant the Name of God, the person continues coming and going in reincarnation, crying out in pain” (Guru Granth Sahib Ji, 325). “The blind have forgotten the Name of God. The self-willed people are in utter darkness. Their comings and goings in reincarnation do not end; through death and rebirth, they are wasting away” (Guru Granth Sahib Ji, 19). No one can say which form do you take after death and how many species you have to go through after death. God decides that for you and it is based on how well you live your life.
