Śrīmad-Bhāgavatam · Text 11.14.22
Who is speaking and story frame
धर्म: सत्यदयोपेतो विद्या वा तपसान्विता ।
मद्भक्त्यापेतमात्मानं न सम्यक् प्रपुनाति हि ॥ २२ ॥
dharmaḥ satya-dayopeto
vidyā vā tapasānvitā
mad-bhaktyāpetam ātmānaṁ
na samyak prapunāti hi
Neither religious activities endowed with honesty and mercy nor knowledge obtained with great penance can completely purify one’s consciousness if they are bereft of loving service to Me.
