Description
The place where ears were pierced.

Bhaktivedanta Narayana Gosvami
From the book “Sri Vraja-maṇḍala-parikramā”:
The karṇa-chedana saṁskāra, or ear-piercing ceremony, of the small boys Kṛṣṇa and Balarāma took place here. This village is currently known as Karṇāvala. One can have darśana of Karṇabedha-kūpa, Ratnacauka, and of the deities of Śrī Madana-mohana and Mādhavarāya here.
