यदधर्मकृत: स्थानं सूचकस्यापि तद्भवेत् ।
yad adharma-kṛtaḥ sthānaṁ sūcakasyāpi tad bhavet |
(Śrīmad Bhāgavatam: 1.17.22)
“A performer of adharma’s future destination [i.e., Naraka] shall become that of an informer as well [i.e., even one who only speaks about an act of adharma performed by another also gets the reaction for performing that act of adharma even though one has only spoken of it and not performed it oneself].”
