Blended reading (Sanskrit + English inline)
jagannātha-sevaka ei, nāma — janārdana anavasare kare prabhura śrī-aṅga-sevana
Sārvabhauma Bhaṭṭācārya first introduced Janārdana, saying, “Here is Janārdana, servant of Lord Jagannātha. He renders service to the Lord when it is time to renovate His transcendental body.”
Purport
During Anavasara, after the Snāna-yātrā ceremony, Lord Jagannātha is absent from the temple for fifteen days so He can be renovated. This occurs annually. Janārdana, who is here being introduced to Śrī Caitanya Mahāprabhu, was rendering this service at the time. The renovation of Lord Jagannātha is also known as Nava-yauvana, which indicates that the Jagannātha Deity is being fully restored to youth.
