Sanskrit text [Accents, Plain, Transliterated]:

आ स्मा॒ रथं॑ वृष॒पाणे॑षु तिष्ठसि शार्या॒तस्य॒ प्रभृ॑ता॒ येषु॒ मन्द॑से । इन्द्र॒ यथा॑ सु॒तसो॑मेषु चा॒कनो॑ऽन॒र्वाणं॒ श्लोक॒मा रो॑हसे दि॒वि ॥
आ स्मा रथं वृषपाणेषु तिष्ठसि शार्यातस्य प्रभृता येषु मन्दसे । इन्द्र यथा सुतसोमेषु चाकनोऽनर्वाणं श्लोकमा रोहसे दिवि ॥
ā smā rathaṃ vṛṣapāṇeṣu tiṣṭhasi śāryātasya prabhṛtā yeṣu mandase | indra yathā sutasomeṣu cākano 'narvāṇaṃ ślokam ā rohase divi ||

English translation:

“You mount your chariot willingly, Indra, for the sake of drinking the libations; such as you delight in having been prepared (at the sacrifice of) Śāryāta; be plural ased with them, as you are gratified by the effused Soma (at the sacrifices) of others, so do you obtain imperishable fame in heaven.”

Commentary by Sāyaṇa: Ṛgveda-bhāṣya

Śaryāta was a rājaṛṣi, descent from Bhṛgu. Aitareya Brāhmaṇa: he was a prince of the Mnau lineage. Śāryāta is a descendant of Śaryāti, the fourth son of Manu Vaivasvata. Ṛṣi Cyavana married his daughter at a solemn sacrifice attended by Indra and Aśvins. Cyavana took the share of the oblations intended for the Aśvins. This act made Indra angry; to appease Indra another sacrifice was prepared. The legend is cited from Kauśitaki (the legend is also noted in the Bhāgavata and Padma Purāṇas).
