"In Paramatma Sahita, [ Sankara says] that the Supreme Self regards him as His very self. The self in the body is generally absorbed by the world of dualities, cold and heat, pain and pleasure but when it controls the senses and masters the world, the self becomes free when the self is bound by the modes of Prakriti or nature as it is called Kshetragna, when it is freed from them, the same self is called the Supreme Self."
