瑜伽師地論略纂 16.34

16.34

Regarding "the five dharmas that sustain concentration": the first is "seclusion," which is the concentration's seclusion from afflictions; the second is "the place of seclusion," which refers to the place where concentration is cultivated and the verbal teachings that conform to concentration; the third is "requisites conforming to an undefiled mind," namely bedding and seats situated at the edge; the fourth is the passage below beginning with "from the wise"; the fifth is the passage below beginning with "regarding all worldly...". Another explanation: seclusion and the place of seclusion constitute the first; the passage below beginning with conforming to an undefiled mind is the second; from those who have suffering below is the third; regarding all samādhis below is the fourth; the previous fifth is divided into two, with uncontaminated practice serving as the fifth.
