One can perform the fivefold Sāma worship in all kinds of water. The coming together of scattered clouds is hiṃkāra. That which pours forth rain is the prastāva. The udgītha is that (river) running eastward, and that which runs westward is the pratihāra. The sea is the nidhana.
He who performs the fivefold Sāma worship in all forms of water, knowing it thus, will never be drowned in water unless he wishes to be, and he will have as much water as he wants.
