5.97

論。七者至勇猛不法　釋曰。能了真如佛正因。故知一切法即是涅槃。於所求果無慮不成。於已學法不怯。修行雖在生死而知幻夢。無惓而勇。無怖而猛。雖復名處亦無怯也。

[Treatise:] Seventh, [they transcend sorrow and regret and are] vigorous and fearless [in the Dharma of saṃsāra].
[Commentary:] Being able to understand that tathatā is the correct cause of Buddhahood, one therefore knows that all dharmas are just nirvāṇa. Regarding the fruit sought, there is no worry that it will not be accomplished; regarding the dharmas already studied, there is no cowardice. In cultivation, although one is in saṃsāra, one knows it is an illusion and a dream; without wearying, one is energetic; without fear, one is bold. Even in [terrifying] situations, one also has no cowardice.
