釋禪波羅蜜次第法門 6.104

6.104

復次，行者如是觀時，眼見色壞，故名過色。耳聲、鼻香、舌味、身觸覺壞，故名滅有對相。於二種餘色及無教色種種不分別，故名不念種種別異相。一切色法既滅，但一心緣空，念空不捨，即色定便謝，而空定未發，亦有中間禪。爾時慎勿憂悔，勤加精進，一心念空，當度色難。是則略說修習禪定方法。

Furthermore, when the practitioner contemplates in this way, the eyes see the disintegration of form, and so it is called 'transcending form'. The sounds of the ear, fragrances of the nose, tastes of the tongue, and tangibles of the body are perceived as disintegrated, and so it is called 'the cessation of the perception of sensory impingement'. Not making various distinctions regarding the two kinds of remaining form and unmanifest form is called 'not attending to various distinct marks'. Once all physical phenomena are extinguished, one single-mindedly conditions [the mind upon] space and attends to space without letting go. The form absorption then wanes, but the space absorption has not yet arisen, and there is also an intermediate dhyāna. At that time, be careful not to feel regret or distress; exert vigorous effort, single-mindedly attend to space, and you will cross over the difficulty of form. This is a brief explanation of the method of cultivating and practicing this absorption.
