The concept of kaivalya (literally, 'aloneness') is of crucial importance to the systems of classical Indian philosophy known as Sākhya and Yoga. Indeed, kaivalya is the supreme soteriological goal to which these systems are directed. Various statements concerning this final goal appear in the classical texts - namely, the Sākhyakārikā and Yogastra - and yet there is no consensus within modern scholarship about how the concept is to be interpreted. More specifically, there appears to be a great deal of confusion (...) over the implications of kaivalya for the existence of the empirical world. In this article I discuss the principal difficulties encountered by existing interpretations of kaivalya, and propose that these difficulties result from an unwarranted assumption that Sākhya and Yoga take a realist view with regard to the empirical world. I further propose that these difficulties can, in large part, be overcome when the assumption of realism is set aside. (shrink)
