Dear ILs, Wishing you all a very Happy Pongal. Subam Karodhi Kalyanam Arogyam Dhanasampadaha Chathru Buddhi vinasaya Deepa jyothir namosthuthe I have opened this thread to ask something about Nandha vilakku. Today, I lit a pancha mugha vilakku at home and went to temple and returned. After reaching home, something suddenly struck me and I wanted to continue lighting this vilakku (Making it a Nandha Vilakku) for the next few days (48 days or so) without letting it go as I learnt that Magara Sankaranthi is an auspicious day to start any good work. Are there any rules for lighting Nanadha Vilakku? For ex, 1. Should Nandha vilakku be lit only in temple or can be lit in home too? 2. When lit in temple, they lock the doors in the night. How about in the house? Should we not lock our house till the period is over? I heard one lady say this. 3. Is it essential to light only one wick? can we light pancha mugam (5 faced vilakku) 4. If lit in our house how about sweeping and moping the house when the vilakku is still burning? I have usually seen people avoiding moping the floor or sweeping after lighting vilakku. What to do if I want to sweep and mop the floor. I sweep floor everyday and mop it alternate days or once in two days. Else it will be dirty since we have a pomeranian dog living with us. 5. what to do during periods? Can it continue burning? Or can my husband continue to pour oil ? 6. Should it be lit for a period of 48 days minimum or can it be for 24 or even lesser no. of days? I ask this because of situations and circumstances, maintaining it for a period of 48 days is what I want to do but, suppose if that's not possible, what to do? 7. Should the house be cleaned in and out before lighting or its okay if I light to light the deepam with normal cleanliness in the house. 8. Can we use an ordinary earthen lamp for this or should use only lamp with other materials that are in bronze or something? Or is there any special vilakku called nandha vilakku that is used in homes too apart from temples which are usually somewhat big. Dear ILs, pls guide me on this. I am eagerly awaiting your reponse. Special Regards, Tinku.
