There are three types of Achamana methods – Śrauta Āchamanam, Smṛtyāchamanam, and Purāṇāchamanam. Their mantras are given below. Place the right hand in the shape of a cow's ear (Gokarṇākṛti), take water from the Pañcapātra with the Udṁdharinī using the left hand, pour it into the right palm, and drink it silently.
