As per video we do provide big diya ( Oil Lamp)  for litting them up for long time for any rituals. Akhand Jyot wick is easy to adjust compare to other cotton wick because of its thickness and way its made . We have 2.75 inch and 3.6 diameters ones available. This brass lamp/diya comes with one Akhand Jyot ( Cotton long thread as shown )
