摩訶止觀 2.120

次、根鈍無遮者，佛世之時周利槃特示是其人。雖三業無過，根性極鈍，九十日誦鳩摩羅偈：「智者身口意，不造於諸惡，繫念常現前，不樂著諸欲，亦不受世間，無益之苦行。」今時雖持戒行善，不學止觀，未來無遮而悟道甚難。

Next, dull faculties without hindrances: in the Buddha's time, Cūḍapanthaka exemplified such a person. Although he had no faults in the three karmas, his faculties were extremely dull, so that for ninety days he recited the verse of Kumāra: 'The wise person in body, speech, and mind / Does not commit any unwholesome deeds; / Keeping mindfulness constantly present, / Does not delight in or attach to desires, / Nor undergo the world's / Profitless austerities.' Today, although one may uphold the precepts and practice good, if one does not study calming and contemplation, though there will be no hindrances in the future, awakening to the Way will be extremely difficult.
