Ever wondered why we light so many lamps in the month of Kartika ?
Itâ€™s one day for the Devas, when Earth goes around the Sun in twelve months. Lord Vishnu goes to sleep on Ashadha suddha ekadashi(some time in July) and wakes-up on Karthika suddha ekadashi. Thatâ€™s why the following day, Karthika Shuddha Dwadashi is observed as â€˜utthaana Dwadashiâ€™. In Sanskrit, â€˜utthaanaâ€™ means â€˜waking upâ€™. When Karthika maasa begins, itâ€™s an hour before waking up and is pitch dark for the Devas. Thatâ€™s the reason we light lamps in the month of Karthika.
