Investigating the ontological and epistemic status of “nothingness” in the Cūḷasuññatasutta

In the Cūḷasuññatasutta (MN 121) , the Buddha discusses a meditative attainment characterized by “nothingness” which is then used as a predicate in an analysis of emptiness. > Furthermore, a mendicant—ignoring the perception of the dimension of > infinite space and the perception of the dimension of infinite > consciousness—focuses on the oneness dependent on the perception of > the dimension of nothingness. Their mind leaps forth, gains > confidence, settles down, and becomes decided in that perception of > the dimension of nothingness. They understand: ‘Here there is no > stress due to the perception of the dimension of infinite space or the > perception of the dimension of infinite consciousness. There is only > this modicum of stress, namely the oneness dependent on the perception > of the dimension of nothingness.’ They understand: ‘This field of > perception is empty of the perception of the dimension of infinite > space. It is empty of the perception of the dimension of infinite > consciousness. There is only this that is not emptiness, namely the > oneness dependent on the perception of the dimension of nothingness.’ > And so they regard it as empty of what is not there, but as to what > remains they understand that it is present. That’s how emptiness > manifests in them—genuine, undistorted, and pure. I am interested in an investigation that addresses such issues as: **Ontological status of “nothingness”:** ---------------------------------------- Is the sphere of nothingness presented as a phenomenal object of experience, a negation of specified classes of objects (e.g., form, infinite space, infinite consciousness), or as a structural absence of cognitive content? Phenomenological description: ----------------------------- In the Cūḷasuññatasutta, the meditator attends to the dimension of nothingness. How is it possible for the mind to intentionally “perceive” something that is, by definition, an absence? Does the sutta imply a particular structure of consciousness that allows an absence to be an object of experience? Nothingness and self-reference ------------------------------ In perceiving nothingness, does the meditator’s mind retain any self-referential awareness, or is subjectivity suspended? How does the sutta articulate the boundaries of selfhood and cognitive agency in relation to the sphere of nothingness? Temporal and spatial character of nothingness --------------------------------------------- The sutta uses the term āyatana, often translated as “dimension” or “sphere.” Does this imply that this nothingness has a kind of temporal or spatial extension, or is it entirely devoid of such characteristics?
