I once read on old folk story about a group of holy sages in India who spent their lives creating havans and doing spiritual work for their Creator. Because of this sacred purifying fire ritual, they wore protective garb made from textiles dyed in cows urine to make the fabric fire retardant and fire repellent. In order to create a urine with these properties, the sages practiced a protocol of keeping the cows hungry for a few days and feeding them only fresh mango leaves. Afterwards, the first urine collected was used to dye the selected fabric. Now, I’ve heard of fire retardant applications and even used fire retardant spray myself, but cow urine as a fire retardant, now that is news to me!
