If water is mixed with milk, fruit juice or other similar substances, it increases their volume, and no one can understand which has increased. In return for this benediction, water accepted one fourth of Indra’s sinful reactions. These sinful reactions are visible in foam and bubbles. Therefore one should avoid foam and bubbles while collecting drinking water.
