ITRANS:
ācāryaṁ jñāna-sampannaṁvastrābharaṇa-dhenubhiḥtoṣayed ṛtvijaś caivatad viddhy ārādhanaṁ hareḥ
Translation:
One should satisfy the spiritual master [ācārya], who is very learned in Vedic literature, and should satisfy his assistant priests [known as hotā, udgātā, adhvaryu and brahma]. One should please them by offering them clothing, ornaments and cows. This is the ceremony called viṣṇu-ārādhana, or worship of Lord Viṣṇu.
