The Order of the Thelemic Golden Dawn. Do what thou wilt shall be the whole of the Law. It is the magical power of devotion, which is the determination to perform and accomplish your True Will, and this without lust of result.
Devotion is a reward unto itself.
Those of us who are devotees of the Great Work exercise devotion, not as a means of obtaining results, but as a discipline to be exercised for its own sake. It is the Love of the Lover, and the Pure Aspiration to unite with the object of his Love. In the East there is a form of Yoga called Bhakti. Bhakti is defined as the Yoga of Devotion or the Yoga of Love. It is our love and devotion for the Great Work that ensures its success.
