‘Dhuni’ is the Sacred fire that perpetually burnt before Baba in ‘Dwarkamai’ mosque. He always used to sit by the side of ‘Dhuni’ and look at it deeply absorbed in thought. During the first period of His stay in this mosque Baba used to put wood collected by Him as also cow dung cakes and keep the fire burning. In later years, devotees started taking care of the fire. They started putting sandalwood, ghee (clear butter), incense into it. Baba used to put His old cloth at the time of change and food items into the fire. The Sacred Ash (popularly known as UDI ) had curative powers in it and whosoever visited Shirdi used to carry it with him in huge quantity. Today, due to the visit by a large number of devotees, a spoon full of this Ash is given. Guruji Shri C. B. Satpathy has brought fire lighted from this Dhuni of Baba and kept in burning continously at Shirdi Sai Baba temples at Injambakkam(Chennai), Chattarpur(New Delhi), and Lapung(Ranchi, Bihar).

     Fire is a manifestation of energy of which the whole universe is made. The fire sacrifice stands for the cosmic consciousness in which the manifold creation is projected, maintained and constantly transformed. Hence, the ‘Dhuni’ is the symbol of ‘Chidagni’ or Cosmic energy.

     ‘Dhuni’, which is perpetually burning at Shirdi, is the fire sacrifice for burning down the sins to ashes for those who seek complete refuge in this peerless Master.

     Baba used to distribute the 'Udi', ash of this sacred fire to all who came to Him with faith, as a token of His grace. Today also the devotees partake a pinch of his sacred ash as a token of his blessings
