अधर्मं धर्ममिति या बुद्ध्यते तमसान्विता ।
सर्वार्थान्विपरीतांश्च बुद्धिः सा तामसी मता ॥
१८-३२ ॥
adharmaṃ dharmamiti yā buddhyate tamasānvitā |
sarvārthānviparītāṃśca buddhiḥ sā tāmasī matā ||
18-32 ||
The intellect that, enveloped in darkness, conceives adharma as dharma and all things in reverse — that is held to be tāmasic.
