Kali Chaudas is known as NarkiChaturdashi. Lord Krishna killed demon Narkasur today and liberated 16,100 maidens from his prison. To save their honour, Lord Krishna later married all these maidens and took them to Dwarika. In verse 127 of Shishapatri, Lord Swaminarayan has asked Acharya MaharajShree to perform ritual worship of Hanuman on this day.

To keep this in mind, Hanumanji is worshipped in all our temples on this day. Legend has it that on the eve of the first anniversary of His coronation, Lord Ram was giving appropriate and suitable gifts to all who helped Him in the battle against demon Ravan. Lord Ram gave a very expensive pearl necklace to Hanuman. On receiving the necklace, Hanumanji started breaking open all the pearls. On being asked why, he said he is looking for Lord Ram in each pearl as he did not want anything which is devoid of Lord Ram. Sitaji asked him if his body has Lord Ram in it. Hanuman opened his chest by his hands and showed Lord Ram in his heart.

Lord Ram was very pleased with this devotion and asked hanuman for a boon. Hanuman asked to be always present wherever and whenever the Leelas of Lord Ram are being sung. As people are still singing Lord Ram's Leela till today, Hanuman has become immortal. This day is considered the second birth of Hanuman as a great devotee. Since then Hanumanji is worshipped on the day Kali Chaudas.
