20.411

第七幾種門，略有三種。一者、有相，謂純思惟分別影像；二者、尋求偏於彼彼未善解了一切法中，為善了故作意思惟一切諸法；三者、伺察謂善解了諸法，為欲證得解脫故作意思惟。如是三觀漸增長故有勝劣，辨止中即由隨前無間三觀心故如次有三也。或八、或四，如文。

Section seven: The gate of how many kinds. In brief, there are three kinds. First, with signs, which means purely contemplating conceptualized images. Second, seeking, which means directing attention to contemplate all dharmas specifically among those dharmas that one has not yet well understood, in order to understand them well. Third, investigating, which means having well understood dharmas, directing attention to contemplate them in order to realize liberation. Because these three contemplations gradually increase, they have degrees of superiority and inferiority. In distinguishing śamatha, precisely by immediately following the preceding three minds of contemplation, there are correspondingly three. Or there are eight, or four, as in the text.
