B.G 17.12

abhisandhāya tu phalaṃ dambhārthamapi caiva yat। ijyate bharataśreṣṭha taṃ yajñaṃ viddhi rājasam ॥12॥

vidhihīnamasṛṣṭānnaṃ mantrahīnamadakṣiṇam। śraddhāvirahitaṃ yajñaṃ tāmasaṃ paricakṣate ॥13॥

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.

"yāgāttu rājasāt svargaḥ sāṅkalpika udāhṛtaḥ। lokaḥ sa dīnadevānāṃ sanāmnāṃ vāsavādibhiḥ॥

viṣṇāvaśraddhayā'yogyakāmāccaiṣāṃ punarbhavet। narakaṃ ca vinā yajñaṃ rājasā naralokagāḥ॥

niṣiddhaṁ karma kuryuścedīyuste narakaṁ dhruvam। kadācit sāttvikāḥ kuryuḥ karma rājasatāmasam॥

anye'nyacca tathāpyeṣāṃ sthitiḥ svābhāvikī punaḥ। svaṃ svaṃ karma tu sarveṣāṃ sadaiva syānmahāphalam॥ anyadalphaphalaṃ caiva bāhulyaṃ teṣu lakṣaṇam॥

"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."
