QUOTE : Sufis have no set belief or disbelief. Divine light is the only sustenance of their soul, and through this light they see their path clear, and what they see in this light they believe, and what they do not see they do not blindly believe. Yet they do not interfere with another person's belief or disbelief, thinking that perhaps a greater portion of light has kindled his heart, and so he sees and believes that the Sufi cannot see or believe. Or, perhaps a lesser portion of light has kept his sight dim and he cannot see and believe as the Sufi believes. Therefore Sufis leave belief and disbelief to the grade of evolution of every individual soul. The Murshid's work is to kindle the fire of the heart, and to light the torch of the soul of his mureed, and to let the mureed believe and disbelieve as he chooses, while journeying through the path of evolution. But in the end all culminates in one belief, Huma man am, that is, 'I am all that exists'; and all other beliefs are preparatory for this final conviction, which is called Haqq al-Iman in the Sufi terminology.
