THE CRUCIBLE OF LIGHT provides in a single volume the definitions of more than 150 fundamental Sufi concepts and terms. In the style of his groundbreaking Sufi Symbolism series, Dr Javad Nurbakhsh illustrates each concept and term with examples of usage culled from the classical writings of Persian Sufism, many of which have never before been translated into English. However, in this new work, he introduces each entry with his own clear explanation. This work is therefore an indispensable tool for any serious study of the writings of the most influential masters of the Sufi tradition, such as Rumi, Hafiz, Ibn Arabi, Bayazid, Ansari and Ruzbihan Baqli and will be a source of joy and inspiration for all lovers of spirituality in general.
