HARĪ LĀL, BHĀĪ, and his brother, Bhāī Krishan Lāl, Brāhmaṇs of Kāshī who, disregarding caste prejudice and pride, joined the Sikh faith in the time of Gurū Arjan. According to Bhāī Kāhn Siṅgh, Gurushabad Ratanākar Mahān Kosh, ślokas in Sahaskritī, a contemporary variety of Sanskritized diction, were composed by the Gurū for their instruction. The main point of this composition is that, of all gifts of God, the gift of His name is the most precious. Harī Lāl and his brother dedicated themselves to spreading the message of Gurū Nānak and established saṅgats in the region of Kāshī (present Vārāṅasī) .
