Notably he had introduced the unique concept of ＂emptiness＂ （gnyata） to explain the Middle Path philosophy： the philosophical meaning of ＂emptiness＂ is dependent co-arising of various elements that support the worldly experience. This study investigates how this concept is used in explaining the subjectivity of a human person and how it is used for interpreting the unique process of human existence. The discussions on subjectivity are imprecise in modern and contemporary philosophy. But Ngrjuna＇s philosophy enables us to explain subjectivity conclusively, without it having to be explained using metaphysical positions. Sunyata may introduce a new definition for the concept of non-self： not for negating the self but for caring self from the problems of life by making it centered in the Middle Path （madhyama-pratipat）, where one may naturally be able to use his wisdom （prajh） as the guiding principle： not mere knowledge （na）. Sanyat is understood using fourfold （catus.kot.i） logical analysis, not twofold analysis employed normally by other philosophers.
