But before the 'heavenly stream' divides into these four branches, it encircles Meru through seven channels for a space of 84,000 yojanas. After its division, each stream falls from the immense height of Meru into a lake from which it flows towards the ocean and in doing so it 'falls' on various mountains. Thus there are four corresponding lakes, Arunodā in the east of Meru, Manasā in the south, Sītodā in the west and Mahābhadra in the north.
