Based on Chapter 33 of the Sree Sai Samartha Satcharita, here is the discussion on the nature, uses, and preparation of Udi:
What is Udi?
Udi is the sacred ash taken from the dhuni, the eternally burning fire kindled by Shirdi Sai Baba in the Masjid. It is regarded by devotees as a miraculous and holy substance that embodies Baba’s power and grace.
Preparation by Baba
Baba prepared Udi by offering an oblation of firewood (logs and sticks) into the dhuni. He purchased this wood using the dakshina (monetary offerings) collected from devotees, piling it in large heaps to keep the fire burning day and night. The resulting ashes were then distributed to his followers as a blessing.
Uses of Udi
The sources categorize the significance of Udi into both material and spiritual realms:
- Material World (Health and Prosperity): Udi is frequently used to cure physical and mental ailments. The text states there are “innumerable stories” where Udi was used to benefit the health and prosperity of devotees, acting as a “healing touch in the afflictions of life”.
- Devotional and Spiritual (Destruction of Sins): Spiritually, Udi serves as a reminder of the transience of the human body and the illusory nature (Maya) of the universe. It teaches that the body will ultimately be reduced to ashes, prompting a focus on the eternal Brahman. Applying Udi with devotion is said to destroy sins and help seekers cross the “ocean of existence”.
Notable Instances of its Power
The sources describe two specific instances where Udi—or even road dust used in its stead—demonstrated Baba’s omnipresence:
- The Jamner Miracle: When Nana Chandorkar’s daughter was suffering from intense labor pains in Jamner, Baba felt compassion from Shirdi. He sent a packet of Udi with Gosavi Ramgir (Bapugir) to Nana. Nana gave the Udi to his wife to administer to their daughter with water, resulting in an immediate safe delivery.
- The “Road Dust” Incident: In another case, a devotee’s daughter was suffering from the plague. Her father sent a message to Nana Chandorkar asking for Udi. Nana, who was at Thane railway station and had no Udi with him, picked up a little dust from the ground, invoked Sai Baba’s name, and applied it to his own wife’s forehead on behalf of the girl. At that exact moment, the girl’s fever broke and she began her recovery.
