utthitaḥ sadaso madhye
tārāṇām uḍurāḍ iva
According to the Vedic system, the reception of great, exalted personalities, as arranged by Pṛthu Mahārāja in that great sacrificial arena, is very important. The first procedure in receiving guests is to wash their feet, and it is learned from Vedic literature that one time when Mahārāja Yudhiṣṭhira performed a Rājasūya-yajña, Kṛṣṇa took charge of washing the feet of the visitors. Similarly, Mahārāja Pṛthu also arranged for the proper reception of the demigods, the saintly sages, the brāhmaṇas and the great kings.
