(Deen). The word deen indicates the 'life transaction' between Allah and Man. It is not merely religion in the constricted and limited sense which the word has assumed in these times. This 'life transaction' is between Allah and man, between the Creator and the created, the Limitless and the limited, the One and the many. 'Life transaction' means every facet, every aspect of life - from the smallest detail to the greatest action. Every moment of a man's life should be impregnated with the awareness of Allah - life is meaningless and futile without such an awareness. Islam, the Perfect and Final Revelation, is the Straight Path to this awareness of the Source. And the higher teaching is the Living Heart of Islam - the Heart from which flows the life-giving nourishment to every soul in the manifested world.
