Explanation:
According to science the soul is formed in this birth alone and is destroyed in this birth itself. The soul functions only as long as food is digested. When the food is not digested due to disease or damage, the person dies. In death, the soul is not destroyed but exits. This exit of the soul from the body is not accepted by science and we differ from science in that. But this does not mean that we are refusing the concept of conversion of food into the soul.
Note:
At the time of death does the soul enter another medium?
The jiva leaves the body only by entering a new medium. As soon as the jiva leaves a body in death, an energetic body is formed. If the soul is to go to hell, the energetic body taken is called as a yatana shariram (body of pain) and if it is to go to heaven, the body taken is called as a bhoga shariram (body of pleasure).
The soul does not require any food when it is in an energetic body. The soul is basically energy and it is present in an energetic body after death. When it is present in the material gross body the energy is gained from matter (process of digestion of food). The conversion of matter into energy takes place only when the soul is present in the material gross body. When it is present in the energetic body, the energy is supplied from the energetic body itself. That energetic body in turn gains energy from the cosmos by the arrangement of God.
