Sūta said: One who has external cleanliness should practise internal cleanliness too. The holy bath should be conducted in accordance with the injunctions. It is threefold: (1) Agneya (fiery), (2) Vāruṇa (watery) and (3) Brāhma (consisting of Brahman). It is only after he has practised the external bath that he should practise the internal. If he is devoid of internal purity, he is still dirty even if he applies clay over his body and plunges into the waters of the tīrthas. O excellent brahmins, the moss, the fishes, the sharks and the animals that prey upon fishes remain ever in water. But are they pure? Internal cleanliness should always be pursued in accordance with the injunctions.
