有說：滅定起心相應有空無願無相三觸，如其次第出滅定時觸於三觸。有餘師說：識處空處心相應觸名不動觸，此二純作識空相故，無所有處心相應觸名無所有觸，無先所有故，非想非非相應觸名無相觸，想無想相不分明故，即由此故說四無色，若有想定從滅定起心通有漏無漏，滅定起時或逆次第入諸等至，或逆超越入諸等至，容有起滅定心現在前故。

Some say: Conjunction with the mind emerging from the concentration of cessation has the three contacts of emptiness, wishlessness, and signlessness, which respectively touch the three contacts when emerging from the concentration of cessation. Other masters say: The contact conjoined with the mind of the station of consciousness and the station of space is called immovable contact, because these two purely form aspects of consciousness and space; the contact conjoined with the mind of the station of nothingness is called nothingness contact, because of the absence of previous existence; the contact conjoined with neither conception nor non-conception is called signless contact, because the signs of conception and non-conception are indistinct. Precisely because of this, it speaks of the four formless [attainments]: if a mind with conception emerges from the concentration of cessation, it is open to being tainted or taintless; when emerging from the concentration of cessation, one either enters the various attainments in reverse order or enters the various attainments skipping in reverse, because the mind emerging from the concentration of cessation is capable of becoming present.
