Those fearful and greatly powerful sons of Dano live in the nether regions. Even all the celestials put together are in capable of fighting with them. The blessed Vishnu, the slayer of Madhu, he who was known on earth as Kapila,
पातालवासिनो रौद्रा दनोः पुत्रा महाबलाः। सर्वदेवनिकाया हि नालं योधयितुं हि तान्॥ योऽसौ भूमिगतः श्रीमान् विष्णुर्मधुनिषूदनः। कपिलो नाम देवोऽसौ भगवानजितो हरिः॥
