成唯識論了義燈 7.212

7.212

《論》：「如入二定說斷苦根」。問：初定無苦，習氣應除，何故二定方始說斷？答：以初靜慮猶有三識，是苦所依；第二定無，是故說斷。問：憂、喜、樂受依於意根，云何初定憂言出離？答：五識自無治道，識無麁重方除；意地自有斷道，憂在初定即滅。離喜、樂等，准此應知。

The Śāstra says: "Just as upon entering the second dhyāna, the faculty of pain is said to be abandoned." Question: The first dhyāna lacks pain, so its latencies should be eliminated; why is it only in the second dhyāna that it is said to be abandoned? Answer: Because the first dhyāna still has the three consciousnesses, which are the basis for pain; the second dhyāna lacks them, and therefore it is said to be abandoned. Question: The feelings of grief, joy, and pleasure rely on the mental faculty; why is grief said to be renounced in the first dhyāna? Answer: The five consciousnesses of themselves have no antidotal path; only when consciousness is absent is heaviness removed. The mental ground has its own path of abandonment; grief is extinguished right in the first dhyāna. Separating from joy, pleasure, and the like should be understood by analogy with this.
