KĀLĀ, BHĀĪ, and his fellow-hillsmen, Bhāī Mehrā and Bhāī Nihālū, all devout Sikhs, once went to Amritsar to see Gurū Arjan. They asked a question : "O support of the supportless! Amritsar is a holy place no doubt, but if some habitual sinners come and settle here, how shall they be liberated?" "A spot which leads to virtuous living must do good to the sinners as well, " said the Gurū.
