Then, with the water of that proksaniya vessel he should sprinkle the area where the Deity is being worshiped, the offerings that are going to be presented, and his own body. Next he should decorate with various auspicious substances three vessels filled with water.
Srila Sridhara Svami gives references from Vedic literature stating that the water meant for bathing the feet should be combined with millet seeds, durva grass mixed in water, visnukranta flowers and other items. The water used for arghya should include the following eight items: fragrant oil, flowers, unbroken barleycorns, husked barleycorns, the tips of kusa grass, sesame seeds, mustard seeds and durva grass. The water for sipping should include jasmine flowers, ground cloves and kakkola berries.
