俱舍論頌疏論本 23.11

23.11

釋曰：言彼居者，彼觀行者居此總雜法念住也。總觀身等四所緣境，修四行相，謂非常等。前別相位有雜緣者，或二、三、四。今此雜緣唯總相緣四，與前別故。總相念住，唯是總雜法念住也。

The explanation says: As for "Abiding in that": that practitioner of contemplation abides in this general mixed application of mindfulness to dharmas. One contemplates collectively the four objects supported by body, etc., cultivating the four modes, namely impermanence and so forth. In the previous specific-characteristic stage, those with mixed objects were either two, three, or four. Now this mixed object takes only all four as a general-characteristic object, differing from the preceding; the general-characteristic application of mindfulness is exclusively the general mixed application of mindfulness to dharmas.
