It is said that, when Sri Ramachandra liberated the Demon Ravana, on the day of Dussehra, it was a time of great celebration!

Diwali represents welcoming the Lord in our homes
and into our lives and hearts.

As our Acharya Srila Bhaktivinoda Thakur says in his beautiful songs:

My Lord, I offer the ghee lamp of my love to You
in the altar of my heart.

Ghee lamp means Dipa…..Dipawali
Hare Krishna, Purusottama Tirtha dasa
