Bhai Bhullu, a Sekhar Khatri who became a mendicant, once waited upon Guru Arjan to seek instruction. He was accompanied by Bhai Nau, also a mendicant like him, Bhai Jattu, a Bhiva Khatri, and Bhai Mula. The Guru said neither action nor the world should be shunned. What was important was shunning evil and temptation, serving others and practising the sacred Word. Bhai Bhullu and others, says Bhai Mani Singh, Sikhan di Bhagat Mala, followed the Guru's precept and were blessed.
