28.16

Regarding "The three, such as boundless space, derive their names from preparation": this means that prior to cultivating concentration, in the preparatory stage, because one turns away from the objective realm of form, one forms an act of resolve and contemplates boundless space; when the preparation is accomplished, it is called the 'sphere of boundless space.' Furthermore, in preparation, turning away from boundless space, one forms an act of resolve and contemplates boundless consciousness; when the preparation is accomplished, it is called the 'sphere of boundless consciousness.' Furthermore, in preparation, turning away from boundless consciousness, one forms an act of resolve and abandons all possessions, abiding in stillness; when the preparation is accomplished, it is called the 'sphere of nothingness.'
