The "atma" or soul according to Sikhism is an entity or "spiritual spark" or "light" in our body because of which the body can sustain life. On the departure of this entity from the body, the body becomes lifeless – No amount of manipulations to the body can make the person make any physical actions. The soul is the 'driver' in the body. It is the "roohu" or spirit or "atma", the presence of which makes the physical body alive. Many religious and philosophical traditions support the view that the soul is the ethereal substance – a spirit; a non-material spark – particular to a unique living being. Such traditions often consider the soul both immortal and innately aware of its immortal nature, as well as the true basis for sentience in each living being. The concept of the soul has strong links with notions of an afterlife, but opinions may vary wildly even within a given religion as to what happens to the soul after death. Many within these religions and philosophies see the soul as immaterial, while others consider it possibly material. According to Chinese traditions, every person has two types of soul called hun and po (魂 and 魄), which are respectively yang and yin. Taoism believes in ten souls, "sanhunqipo" () "three "hun" and seven "po"". A living being that loses any of them is said to have mental illness or unconsciousness, while a dead soul may reincarnate to a disability, lower desire realms, or may even be unable to reincarnate. In theological reference to the soul, the terms "life" and "death" are viewed as emphatically more definitive than the common concepts of "biological life" and "biological death". Because the soul is said to be transcendent of the "material existence," and is said to have (potentially) eternal life, the death of the soul is likewise said to be an "eternal death". Thus, in the concept of divine judgment, God is commonly said to have options with regard to the dispensation of souls, ranging from Heaven (i.e., angels) to hell (i.e., demons), with various concepts in between. Typically both Heaven and hell are said to be eternal, or at least far beyond a typical human concept of lifespan and time. According to Louis Ginzberg, the soul of Adam is the image of God. Every soul of human also escapes from the body every night, rises up to heaven, and fetches new life thence for the body of man.
