CC Madhya 12.204
mahotsava haila bhaktera prāṇa-samāna
The next day marked the performance of the festival of Netrotsava. This great festival was the life and soul of the devotees.
After the bathing ceremony of Lord Jagannātha, during the fortnight before the Ratha-yātrā ceremony, the body of Lord Jagannātha, having been washed, needs repainting. This is known as aṅga-rāga. The Netrotsava festival, performed gorgeously in the early morning of the Nava-yauvana day, constitutes the life and soul of the devotees.
