You should partake of the sacred water (Theertham) three times while reciting the names “Achyuta, Anantha, Govinda.” This should be done twice (making it a total of six sips). Whenever ritual impurity (ashuddhi) occurs, you should wash your hands and feet, gargle your mouth, and then perform this. Furthermore, it should also be performed after taking a bath. The procedure is explained in detail in the video below.
