The physical body has to tolerate all severe agonies. There are three types of agonies that the human body has to go through – Physical, Metaphysical and Spiritual. Without suffering the agonies the body is not liberated. Even if the physical body is liberated from these agonies,the subtle body (astral body of light) encasing the soul, still has to suffer minutely, while undergoing suferings, the life or the soul in the subtle body has to travel across different universes existing in the astral world. The soul is individual, eternal and independent of physical body. As per the established truth, the soul cannot unite with the infinite Supreme until it breaks all mortal bonds and gets liberated.
