成唯識論演祕 4.348

4.348

《對法》同此。按彼論第五云：「等無間緣者，謂中無間隔，等無間故。」釋論云：「不必剎那中無間隔，雖隔剎那，但於中間無異心隔，亦名中無間隔。若不爾，入無心定心，望出定心，應非等無間緣。然是彼緣，是故於一相續中，前心望後心，中間無餘心隔故，是等無間緣。」

The Abhidharmasamuccaya-bhāṣya agrees with this. Fascicle 5 of that treatise states: "The equal-immediate condition means that there is no interval in between, because it is equally immediate." The Bhāṣya states: "It does not necessarily mean there is no interval between moments; even if separated by moments, as long as there is no different mind intervening in between, it is also called having no interval in between. Were it not so, the mind entering the mindless attainment, with respect to the mind emerging from the attainment, would not be an equal-immediate condition. Yet it is such a condition; therefore, within a single saṃtāna, because the preceding mind has no other mind intervening between it and the subsequent mind, it is an equal-immediate condition."
