gatvā bhuvaṃ samāsādya bhadrāśvājjaladhiṃ gatā /
tathaivālakanandākhyā dakṣiṇe gandhamādane //

The eastern stream, which is celebrated by its name Sītā,[3] flowed to the forest Caitraratha,[4] and overflowing it, passed on to the lake Varuṇoda,[5] and thence to the mountain Śītānta,[6] and thence to the other mountains on the east in order. Descending to the earth in her course, she flowed from Bhadrāśva into the ocean.

Moreover the second stream called Alakanandā flowed south towards Grandhamādana into the forest Nandana that delights the gods and that lies at the foot of Meru, and overflowed the lake Mānasa with great force, and reached the delightful kingly mountain Śikhara,[7] and thence overflowed all the mountains which I have mentioned in order on the south, and reached the lofty mountain Himavat. There the bull-bannered Śiva held her and would not let her go. The lord was propitiated by king Bhagīratha with fastings and hymns, and Śiva released her there. She entered the southern ocean in seven streams, and in three streams on the east; inundating as a great river the south with the overflow from her stream, behind Bhagīratha’s chariot.
