iti te pūrvavṛttāṃtaṃ kathitaṃ nāmakāra ṇam..
sāṃprataṃ tu yathā jātaṃ punaḥ kalakaleśvaram..
tatte'haṃ saṃpravakṣyāmi śṛṇuṣvaikamanāḥ priye .. 7 ..

Thus has the former account been told to you, the reason for its name. / But now, how it became Kalakaleśvara once again, / that I shall relate to you; listen with a single-minded focus, O beloved!
