Yama Deepdan on the day of Dhanteras.

Yamadeepdan on the day of Dhanteras.

Dhanteras is on Tuesday, 02 November 2021.
Yama-Deepdan should definitely be done on this day. By doing this the fear of premature death ends. This is the only day in the whole year when Yamraj, the god of death, is worshiped only by donating a lamp. Some people also donate lamps on the day of Narak Chaturdashi.

It is written in Skanda Purana
कार्तिकस्यासिते पक्षे त्रयोदश्यां निशामुखे ।
यमदीपं बहिर्दद्यादपमृत्युर्विनिश्यति ।।
Om i.e. on the day of Trayodashi of Krishna Paksha of Kartik month, keeping a lamp outside the house for the purpose of Yamdev prevents death.

It is written in Padma Purana
कार्तिकस्यासिते पक्षे त्रयोदश्यां तु पावके।
यमदीपं बहिर्दद्यादपमृत्युर्विनश्यति।।
On the Trayodashi of Kartik Krishna Paksha, a lamp should be given outside the house for Yamraj, this destroys the insurmountable death.

Yama-Deepdan Simple Method
Yamadeepdan should be done during Pradosh period. For this, take a big lamp of flour. A lamp made of wheat flour has the ability to pacify the tamoguni energy waves and the aaptattvatva tamoguni waves (these waves are the cause of apomortisation). After that, take clean cotton and make two long lights. Place them in the lamp on each other in such a way that the four faces of the lights are visible outside the lamp. Now fill it with sesame oil and also put some black sesame seeds in it. Worship the lamp thus prepared during Pradosh Kaal with Roli, Akshat and flowers. After that, outside the main door of the house, make a small lump of rice or wheat and place a lamp on it. Light the lamp before placing it and looking towards the south direction (the south direction is favorable for Yama waves, that is, the Yama waves are attracted and projected in more quantity from the south direction), place the four-faced lamp on top of a pile of cakes etc. Keep it Saying ‘Om Yamdevaya Namah’, salute in the south direction.

Mantra of Yama Deepdan:

मृत्युना पाशदण्डाभ्यां कालेन श्यामया सह |
त्रयोदश्यां दीपदानात् सूर्यजः प्रीयतां मम ||

It means, on Dhantrayodashi, I offer this lamp to the son of Surya i.e. Yama Devata. May he free me from the clutches of death and do my welfare.
