“This is a very special month (Kartik Damodar month), and offering a lamp on this day not only helps you but also your forefathers and also helps your descendants- your children, your grandchildren, even those who are not yet born. So who will not take this opportunity to offer a lamp or do some simple seva.”
H.H. Jayapataka Swami
When one offers a lamp during the month of Kārtika, his sins in many thousands and millions of births perish in half an eye blink.
