Śrīmad-Bhāgavatam · Text 11.17.27
Who is speaking and story frame
आचार्यं मां विजानीयान्नावमन्येत कर्हिचित् ।
न मर्त्यबुद्ध्यासूयेत सर्वदेवमयो गुरु: ॥ २७ ॥
ācāryaṁ māṁ vijānīyān
navamanyeta karhicit
na martya-buddhyāsūyeta
sarva-deva-mayo guruḥ
One should know the ācārya as Myself and never disrespect him in any way. One should not envy him, thinking him an ordinary man, for he is the representative of all the demigods.
