It is the soul’s light which is natural intelligence. by Hazrat Inayat Khan

Commentary by Pir-o-Murshid Inayat Khan Coming to the cause of the lack of joy, one realizes by pondering on the subject that it is not pursuing after joy that results in disappointment, it is the wrong method adopted in the pursuit of joy which brings, instead of joy, sorrow or disappointment. … Nothing can take away joy from the man who has right understanding. Through all conditions of life he will retain it, but the one who lacks understanding, nothing in the world or Heaven there is which can bring him a lasting joy. This shows that, in reality, joy does not come from the external life, though always it seems so. Joy has only one source and that is the heart of man, which is the globe over his soul’s light. ~~~ “Sangatha III, Tasawwuf “, by Hazrat Inayat Khan (unpublished) The soul has the tendency to look forward to what is going to be, or at what has been in the past. It is the light of our soul, the intelligence that does this. Intelligence working through physical means is no greater than intellect. But intelligence working freely and independently from physical means is wisdom. And wisdom is not cleverness, but infinitely superior to it. Wisdom works independently of the physical means, and therefore, requires intuition. The clever person works by means of his physical body, but the wise person works independently of it. from http://wahiduddin.net/mv2/VII/VII_20.htm The Qur’an says, ‘God is the Light of the heavens and of the earth;’ and if there is any spark of God that can be found in man, it is his intelligence. Naturally, therefore, when this divine light which is hidden in man is once brought to a blaze and has risen as a flame, it illuminates his path towards perfection. from http://wahiduddin.net/mv2/VII/VII_39.htm
