妙法蓮華經玄贊 2.284

2.284

贊曰：第四大眾安樂，法食資持禪悅生樂，盡業縛之麁重，何得生於懈倦焉。懈懶、倦疲也。有作「惓」，無所從。

The commentary states: The fourth is the peace and joy of the great assembly. Sustained by the nourishment of the Dharma, they generated joy from the delight of dhyāna, which exhausted the coarseness and heaviness of karmic bondage; how could they produce weariness and fatigue? Xiè means slackness; juàn means exhaustion. Some texts write juàn (惓), but it has no derivation.
