Those about to offer oblations into the fire of sacrifice in accordance with the Ṛg, Yajur and Sāma Vedas meditate on Your lotus feet. Similarly, the practitioners of transcendental yoga meditate upon Your lotus feet, hoping for knowledge about Your divine mystic potency, and the most elevated pure devotees perfectly worship Your lotus feet, desiring to cross beyond Your illusory potency.
