विधिहीनमसृष्टान्नं मन्त्रहीनमदक्षिणम् । श्रद्धाविरहितं यज्ञं तामसं परिचक्षते ॥१३॥
vidhi-hīnam asṛṣṭānnaḿ mantra-hīnam adakṣiṇam śraddhā-virahitaḿ yajñaḿ tāmasaḿ paricakṣate
vidhi-hīnam — without scriptural direction; asṛṣṭa-annam — without distribution of prasādam; mantra-hīnam — with no chanting of the Vedic hymns; adakṣiṇam — with no remunerations to the priests; śraddhā — faith; virahitam — without; yajñam — sacrifice; tāmasam — in the mode of ignorance; paricakṣate — is to be considered.
Sacrifice devoid of faith and contrary to the injunctions of the scriptures, in which no food is offered, no mantras chanted, and no donation made, is to be considered in the mode of ignorance.
Faith in the mode of darkness or ignorance is actually faithlessness. Sometimes people worship some demigod just to make money and then spend the money for recreation, ignoring the scriptural injunctions. Such ceremonial shows of religiosity are not accepted as genuine. They are all in the mode of darkness; they produce a demoniac mentality and do not benefit human society.
