RĀI BULĀR a Muhammadan noble of the Bhaṭṭi clan, was during the latter half of the fifteenth century the chief of Talvaṇḍī Rāi Bhoi, the village where Gurū Nānak was born in 1469. Rāi Būlār had great affection for young Gurū Nānak and held him in high esteem. According to Janam Sākhī accounts, Rāi Bulār perceived the Divine in Gurū Nānak and became a devotee. Once young Nānak was arraigned before him for having allowed the cattle herd he was tending to damage a farmer’s crop. The Rāi sent for Bābā Kālū, the Gurū's father, and directed him to compensate the farmer for the damage. But footmen sent to estimate the loss reported that they had seen no damage whatsoever. Rāī Bulār was as much surprised as the complainant himself, who insisted that he had seen with his own eyes the whole crop ruined and the buffaloes sitting amidst it after they had heartily gorged themselves on it. On another occasion, Gurū Nānak, while out with his herd, lay down to rest under a tree in the summer afternoon and fell asleep. After a while, Rāi Bulār along with his servants happened to pass by. He was surprised to see a strange phenomenon. The shadows of other trees had travelled round with the sun, but not of the tree under which Nānak slept. Returning to the town, the Rāi called Father Kālū and said to him, "Your son is a great man. He is the honour of my town. Kālū, thou hast become exalted and I too am exalted in whose town such a one has been born."
Gurū Nānak reciprocated the honour and affection extended to him by Rāi Bulār and never failed in between his long travels to visit him, who always felt blessed to see him. Even when he lay dying in 1515 circa, the Gurū was by his bedside.
