Janardana (Sanskrit: जनार्दन, romanized: Janārdana) is an epithet of Vishnu in the Puranas.
Janardana means, “he who is the original abode and protector of all living beings”.
[1] His main shrine is the Janardanaswamy temple situated in Varkala In the Mahabharata, Sanjaya uses this epithet of Vishnu to describe the latter's prowess to King Dhritarashtra:[2] You askest me repeatedly, O king, about the Pandavas for knowing their strength and weakness.
That soul of all creatures, most exalted of male beings, Janardana, guides, as if in sport, the entire earth, the firmament, and the heaven.In the Bhagavad Gita, Arjuna invokes this epithet:[3] विस्तरेणात्मनो योगं विभूतिं च जनार्दन । भूयः कथय तृप्तिर् हि शृण्वतो नास्ति मेऽमृतम् ॥ १८ ॥ vistareṇātmano yogaṃ vibhūtiṃ ca janārdana | bhūyaḥ kathaya tṛptir hi śṛṇvato nāsti me'mṛtam || 18 ||
O Janārdana, please tell me again in detail about Your mystic powers and opulences, for I am not satiated from hearing Your nectarean words.
