Gita 17.1
अर्जुन उवाच। ये शास्त्रविधिमुत्सृज्य यजन्ते श्रद्धयान्विताः। तेषां निष्ठा तु का कृष्ण सत्त्वमाहो रजस्तमः॥
arjuna uvāca ye śāstra-vidhim utsṛjya yajante śraddhayānvitāḥ teṣāṁ niṣṭhā tu kā kṛṣṇa sattvam āho rajas tamaḥ
"Arjuna said: Those who set aside scriptural injunctions but worship with faith—what is their status, O Krishna? Is it sattva, rajas, or tamas?"
