Product description Before every Puja or Yagna, the priest ties a sacred thread on the hand of the person who is getting the Puja done. This thread called, Moli, is tied and the person is asked to take a Sankalp which is like a vow, a purpose for which a particular Puja or Yagna is being done. It is tied on hand after the sankalp mantra-indicating a devotee's resolution to worship / do puja etc. Hence the moli is a gross reminder and symbol of this conviction. As the string is tied around the hand, you pray that your life will similarly revolve around God
