Muḥammad ibn Muṣṭafá Khādimī (c. 1702–1763) writes that, "protecting the spiritual heart from worldly thoughts can be accomplished by the spiritual heart's benefiting (receiving "Fayd" (nūr [light]) from the spiritual heart of the perfect Sufi master. The spiritual luminance (Fayd) flows from one spiritual heart to another by way of love. Death of the perfect spiritual guide or his being in a distant country does not stop the flow of spiritual luminance (Fayd)."[22] According to Inayat Khan (1882–1927) the soul is like a ray of the sun.
