Dīpāvalī–Ofrenda y colocación de lámparas (o velas) en los templos de Viṣṇu

Después de catorce años de exilio, el Señor Rāmacandra regresó a Su reino. Los habitantes de Ayodhyā iluminaron la ciudad con lámparas para recibirlo.

Srila Prabhupada explains dipavali (Diwali)

This Dipabali function can be observed on 21st October, and Prasad can be distributed on the 22nd October, during daytime, which is known as Govardhana Puja and Annakuta Ceremony. In India, in all Vaisnava temples, this ceremony is observed and 100’s of people are given Prasad according to the capacity of the temple. So I understand that last year the Dipabali Ceremony was held in the temple, and there was collection of $130.00. So you can do the needful.

Hope you are all well,

Your ever well-wisher,
A.C. Bhaktivedanta Swami
