an.9.32 Aṅguttara Nikāya (Numbered Discourses)

“Monks, there are these nine step-by-step dwellings. Which nine? The first jhāna, the second jhāna, the third jhāna, the fourth jhāna, the dimension of the infinitude of space, the dimension of the infinitude of consciousness, the dimension of nothingness, the dimension of neither perception nor non-perception, the cessation of perception & feeling. These are the nine step-by-step dwellings.”
