The Mouli thread is an integral part of any puja. Normally the Mouli is tied around the Sadhana article, that is Mouli is tied around a copper tumbler filled with water. On its mouth is placed five mango leaves and a coconut in a red cloth is place it over the mouth of the tumbler. This represents the shrine you are offering puja.
