俱舍論記 2.54

2.54

「論曰至三隨念分別」者，自性是尋，尋求動踴，如魚躍水。體即分別，名自性分別。若能計度青、黃等別，男、女等差別，名計度分別。隨念曾更，或隨境念，名隨念分別。

Regarding "The commentary says: ... third is conceptualization by recollection": The intrinsic nature is reflection; searching out and stirring energetically, like a fish leaping from water. Its essence is itself conceptualization, so it is called intrinsic conceptualization (svabhāva-vikalpa). When it can reckon and deliberate the distinctions between blue, yellow, etc., or male, female, etc., it is called conceptualization by reckoning (abhinirūpaṇā-vikalpa). When it recollects what was previously experienced, or is mindfulness following an object, it is called conceptualization by recollection (anusmaraṇa-vikalpa).
