 The Sarvāstivāda adopted a system of seventy-five basic types of dharmas organized into a fivefold categorization. The first four categories comprise all conditioned (saṃskṛta) dharmas and include, again, consciousness (citta, one single dharma); associated mentality (caitta, encompasses forty-six dharmas); and physical phenomena (rūpa, eleven dharmas); but also factors dissociated from thought (cittaviprayuktasaṃskāra, fourteen dharmas). The last category is mentioned neither in the sūtras nor in the Theravāda lists, but is found predominantly in northern Indian Abhidharma texts of all periods. The specific dharmas included within it vary, but they are all understood as explaining a range of experiential events, being themselves dissociated from both material form and thought. The fifth category in the Sarvāstivāda taxonomy, that of the unconditioned (asaṃskṛta), comprises three dharmas, namely, space and two states of cessation (nirodha), the latter being a term that connotes the culmination of the Buddhist path (Cox 1995; 2004A, 553–554).
