Nasma is a body made of the purest form of light (called Noor) which is more pure than any visible color. Shah Wali Ullah was the first who give hints about this body. Qalandar Baba Auliya give its more details while Khwaja Shamsuddin Azeemi thoroughly described that body. This body is actually that is controlling the human physical body. The lights coming from Nasma to material body are visible only through Kirlian photography. These visible lights are called Aura.
