B.G 17.12

अभिसन्धाय तु फलं दम्भार्थमपि चैव यत्। इज्यते भरतश्रेष्ठ तं यज्ञं विद्धि राजसम् ॥१२॥

विधिहीनमसृष्टान्नं मन्त्रहीनमदक्षिणम्। श्रद्धाविरहितं यज्ञं तामसं परिचक्षते ॥१३॥

O best of the Bharatas, know that the sacrifice performed intending fruit, for show, is in the mode of passion.

A sacrifice performed without adherence to the proper procedures, without offering food, without chanting mantras, without giving gifts, and devoid of faith is considered to be in the mode of ignorance.

Gīta Tātparya 17.12 and 13

Those who act without faith in Lord Viṣṇu are driven by unworthy desires and are reborn. If one engages in forbidden actions, they are destined for hell. However, one's own actions in swa-dharma always yield great results.

"यागात्तु राजसात् स्वर्गः साङ्कल्पिक उदाहृतः। लोकः स दीनदेवानां सनाम्नां वासवादिभिः॥

विष्णावश्रद्धयाऽयोग्यकामाच्चैषां पुनर्भवेत्। नरकं च विना यज्ञं राजसा नरलोकगाः॥

निषिद्धं कर्म कुर्युश्चेदीयुस्ते नरकं ध्रुवम्। कदाचित् सात्त्विकाः कुर्युः कर्म राजसतामसम्॥

अन्येऽन्यच्च तथाप्येषां स्थितिः स्वाभाविकी पुनः। स्वं स्वं कर्म तु सर्वेषां सदैव स्यान्महाफलम्॥ अन्यदल्पफलं चैव बाहुल्यं तेषु लक्षणम्॥

"Heaven as described in royal sacrifices is considered imaginary. It is a realm of the lesser gods, named along with Indra and others. Those who act without faith in Lord Viṣṇu, driven by unworthy desires, are reborn; they go to hell and, without sacrifice, are led by passion to the world of men. If one engages in forbidden actions, they are destined for hell. Occasionally, even those who are virtuous may act out of passion or ignorance. Others and another, thus also, the state of these is natural again. However, one's own actions always yield great results. Another's is characterised by abundance, and small results."
