Some call the Lord "Ram, Ram", and some "Khuda". Some serve Him as "Gusain", others as "Allah". He is the Cause of causes, and Generous. He showers His Grace and Mercy upon us. Some pilgrims bathe at sacred shrines, others go on Hajj to Mecca. Some do devotional worship, whilst others bow their heads in prayer. Some read the Vedas, and some the Koran. Some wear blue robes, and some wear white. Some call themselves Muslim, and some call themselves Hindu. Some yearn for paradise, and others long for heaven. Says Nanak, one who realizes the Hukam of God's Will, knows the secrets of his Lord Master. (Sri Guru Granth Sahib Page:885)
