When Guru Ramdas Chose His Youngest Son, Arjanmal, To Succeed Him As The Fifth Guru Of The Sikhs, It Created A Lot Of Ill-Will In His Eldest Son, Prithichand. But The Choice Was Not Wrong. Guru Arjan Was The Very Embodiment Of Love, Humility And Courage. His Greatest Contribution To Sikhism Was The Compilation Of The Guru Granth Sahib And The Construction Of The Har Mandir Sahib In Amritsar. He Was The First Sikh Martyr And By His Death Inspired His Followers To Uphold The Truth Under Any Pressure./A
