"I first believed without any hesitation in the existence of the soul, and then I wondered about the secret of its nature. I persevered and strove in search of the soul, and found at last that I myself was the cover of my soul. I realized that in me which believed and that in me which wondered, that which persevered in me, and that which found, and that which was found at last, was no other than my soul. Since then I have seen all souls as my soul, and realized my soul as the soul of all; and what bewilderment it was when I realized that I alone was, if there were anyone; that I am whatever and whoever exists; and that I shall be whoever there will be in the future. And there was no end to my happiness and joy."
-Hazrat Inyat Khan (Sufi Teacher)
