यस्य साक्षाद्भगवति ज्ञानदीपप्रदे गुरौ ।
मर्त्यासद्धी: श्रुतं तस्य सर्वं कुञ्जरशौचवत् ॥
yasya sākṣād bhagavati jñāna-dīpa-prade gurau |
martyāsad-dhīḥ śrutaṁ tasya sarvaṁ kuñjara-śaucavat ||
(Śrīmad Bhāgavatam: 7.15.26)
“All the hearing of one who thinks guru, who is Bhagavān himself and the giver of the lamp of knowledge, is a contemptible mortal is like the bathing of an elephant [i.e., futile].”
