The Hamsaprapatana tîrtha (the shrine where swans alight), that lies on the north of Pratiṣṭhâna and on the east bank of the Ganges, is renowned in all the three worlds. By bathing there the devotee gets the benefit of Aśvamedha sacrifice and resides in heaven, as long as the the sun and the moon shine in the firmament.—32-33.
