Śrīmad-Bhāgavatam · Text 11.11.20
यस्यां न मे पावनमङ्ग कर्म
स्थित्युद्भवप्राणनिरोधमस्य ।
लीलावतारेप्सितजन्म वा स्याद्
वन्ध्यां गिरं तां बिभृयान्न धीर: ॥ २० ॥
yasyāṁ na me pāvanam aṅga karma
sthity-udbhava-prāṇa-nirodham asya
līlāvatārepsita-janma vā syād
vandhyāṁ giraṁ tāṁ bibhṛyān na dhīraḥ
My dear Uddhava, an intelligent person should never take to literatures that do not contain descriptions of My activities, which purify the whole universe. Indeed, I create, maintain and annihilate the entire material manifestation. Among all My pastime incarnations, the most beloved are Kṛṣṇa and Balarāma. Any so-called knowledge that does not recognize these activities of Mine is simply barren and is not acceptable to those who are actually intelligent.
