The worshiper should then purify those three vessels. He should sanctify the vessel holding water for washing the Lord’s feet by chanting hṛdayāya namaḥ, the vessel containing water for arghya by chanting śirase svāhā, and the vessel containing water for washing the Lord’s mouth by chanting śikhāyai vaṣaṭ. Also, the Gāyatrī mantra should be chanted for all three vessels.
