Sanskrit:
यज्ञेन युष्मद्विषये द्विजातिभि-र्वितायमानेन सुरा: कला हरे: ।स्विष्टा: सुतुष्टा: प्रदिशन्ति वाञ्छितंतद्धेलनं नार्हसि वीर चेष्टितुम् ॥ २२ ॥
ITRANS:
yajñena yuṣmad-viṣaye dvijātibhirvitāyamānena surāḥ kalā hareḥsviṣṭāḥ sutuṣṭāḥ pradiśanti vāñchitaṁtad-dhelanaṁ nārhasi vīra ceṣṭitum
Translation:
When all the brāhmaṇas engage in performing sacrifices in your kingdom, all the demigods, who are plenary expansions of the Lord, will be very much satisfied by their activities and will give you your desired result. Therefore, O hero, do not stop the sacrificial performances. If you stop them, you will disrespect the demigods.
