Uluka was the son of a sage, but he was not very clever. Even though he studied in a gurukula, he could not understand what his teacher taught. One day, the teacher told him to leave if he was not interested in learning. Feeling very sad, Uluka went to a mountain and prayed deeply. God came in the form of an old man and taught him an important lesson. After that, Uluka studied well, became a wise man, and later became a great sage. He was known as Kanada, who started the Vaisheshika school of philosophy and taught about atoms.
