The later Madhyamikas, states Yuichi Kajiyama, developed the "Advaya" definition as a means to "Nirvikalpa-Samadhi" by suggesting that "things arise neither from their own selves nor from other things, and that when subject and object are unreal, the mind, being not different, cannot be true either; thereby one must abandon attachment to cognition of nonduality as well, and understand the lack of intrinsic nature of everything".
