The article considers the philosophical polemics between Buddhism and Mimamsa on the problem of the existence and properties of the self as it is given in the chapter "The Polemics with the Mimamsakas on Atman" of the section -Atmapariksha‖ (lit. -The Study of Atman‖) of -Tattvasamgraha‖ of Shantarakshita (the 8th century) with the commentary -Panjika‖ of Kamalashila. According to the Mimamsakas, atman has a form of consciousness (caitanya) and exclusive and inclusive nature. Exclusiveas the seat of satisfaction and dissatisfaction, etc., which are mutually exclusive states, inclusiveas a sequence of consciousness, essentiality, good qualities, etc. Shantarakshita criticizes the position of the Mimamsakas, revealing contradictions in their internal philosophical logic.
