Upanishads speak of reincarnation. The Bhagavad Gita , one of the Hindu scriptures , details the afterlife. Here Krishna says that just as man leaves his old clothes and puts on new clothes , so also the soul gives up its old body and takes on new body. In Hinduism, it is believed that the body is like a shell , its inner soul is immutable and immortal , and this soul carries a different body in the cycle of birth and death. The end of this cycle is called Mukti or Moksha where this soul merges with God. The Garuda Purana also mentions what happens to a person after death. It is said here that when the time of death of a person draws near, the god of death, Yam, sends his messengers to fetch his soul from the body of the person. Chitragupta, a colleague of Yam, wrote down all the good and bad deeds of that person. According to the Garuda Purana, after the soul leaves the body, it crosses a long and dark tunnel to the south. An oil lamp is lit next to the body of the deceased so that the tunnel is illuminated and the soul of the deceased can go freely. Depending on the actions of the previous birth, the soul will be born with a body in the next birth. If one commits a sin in the previous birth , then in the next birth he will be reborn in an animal or some other inferior being . Between these two births the person is punished in hell for his evil deeds and enjoys peace in heaven for his good deeds. When a person's period of punishment or reward is over, he is sent back to earth, which is also called "death." And in this way, through repeated births and deaths, a person goes through a cycle of life from which he can be liberated only through salvation. The ultimate goal of the Hindus is to attain Moksha which can be attained only through Jnana Yoga according to the Vedas and Karmayoga and Bhakti Yoga according to the Bhagavad Gita. Jnana Yoga refers to the attainment of Samadhi through meditation in the Upanishads and in the Sannyasivas mentioned in the Yoga Sutras . According to karmyoga, giving up hope of karma and giving up self-esteem, that is, doing karma without considering oneself as the master of any work, is called karmayoga. Devotion means surrendering oneself to God and always thinking of God. Salvation is possible through these three paths , that is , the union of the soul with God is possible. Note that according to a Vedanta philosophy called Vishishtadvaitavad, without devotion, it is not possible to attain union with God only through knowledge and action. Somewhere in Hinduism this salvation has been described as a state of extreme bliss , somewhere it has been described as a state of liberation from sorrow , and somewhere it has been described as a state free from all kinds of emotions starting from joy , sorrow. According to the Bhagavad Gita, the soul never dies , only the body dies which is the sum of the five elements - kshiti (soil) , op (water) , tej (fire) , marut (air) , byom (sky). These five elements are called Panchabhuta. None of these five elements can do any harm to the soul or affect the soul. Different types of heaven and hell are described in Garuda Purana. Heaven or hell is determined by what you do on earth. Hindus believe in "action". Action is the sum total of good and bad deeds of a person. Good deeds by good deeds and evil deeds by bad deeds. According to Hinduism, the basic concept of action is "as action , so fruit". So , if a person lives an honest life, he will be rewarded in the hereafter. If you live a wicked life, that wicked deed will be reflected in the next life. Rewards for good deeds and bad fruits for bad deeds , and there is no justice. The person collects action by his actions and even by thought in his lifetime. According to the Bhagavad Gita , Arjuna was hesitant to kill his relatives in the battle of Kurukshetra. Then Krishna in the form of Krishna said to Arjuna , " Do you believe that you are the master of this work ? No. You are merely an instrument in my hand. Do you think that these people in front of you are alive ? O Arjuna , they are already dead. It is your responsibility to protect it. If you do not do this , you will not follow the principles of religion. "
