yo vakti nyāya-rahitam anyāyena śṛṇoti yaḥ |
tāv ubhau narakaṁ ghoraṁ vrajataḥ kālam akṣayam ||
(Nārada Pañcarātra; cited in Hari-bhakti-vilāsa: 1.101; Bhakti Sandarbha: 238)
“Both one who speaks devoid of rule [i.e., instructs things that are contrary to the intent of the śāstra] and one who listens devoid of rule [i.e., follows things that are contrary to the intent of the śāstra] proceed to a dark hell for unlimited time.”
