Sri Caitanya-caritamrta

CC Madhya-lila

Śrīla Bhaktisiddhānta Sarasvatī Ṭhākura remarks, “Which Śrī Śaila is being indicated by Kṛṣṇadāsa Kavirāja Gosvāmī is not clearly understood. There is no temple of Mallikārjuna in this area because the Śrī Śaila located in the district of Dhārwād cannot possibly be there. That Śrī Śaila is on the southern side of Belgaum, and the Śiva temple of Mallikārjuna is located there. (Refer to text 15 of this chapter.) It is said that on that hill Lord Śiva lived with Devī. Also, Lord Brahmā lived there with all the demigods.”
