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 another person performing an act of adharma also gets a share of the reaction for performing that act of adharma even though one has only spoken of the performer of it and not performed the action oneself].”
