I’m ‘into’ mindfulness---which is all about health and wellness---and the essence of mindfulness (which, by the way, is not a religion) is this---unconditional surrender to what is. Such surrender is the result of a choiceless awareness to life as it unfolds from one moment to the next. In essence, the word ‘Islam’ means voluntary and total submission---in peace---to the will of the Almighty (Allah) together with a striving after Truth so as to do the will of Allah. Submission and surrender are essentially the same thing, for both involve a letting-be and a calm acceptance of whatever is. The word ‘Islam’ refers to that total peace that comes from such submission or surrender.
In short, we are talking about an ‘all-Encompassing’ Reality---One Presence and One Power active in the universe. This is the true meaning of the statement, ‘There is no God but Allah’ (Qur’an 47:19). This uncreated and unmanifest Presence is not ‘transcendent’ in the Judeo-Christian sense---at least not in the sense of some supposed anthropomorphic deity in the ‘upper regions’ (whatever that means). No, we are talking about a Reality that is truly limitless, encompassing all things including all of space---and yet beyond all space as well. Nor is this Presence ‘immanent’ in the Christian sense, for the Presence cannot be said to be contained ‘in’ anything. Nor can this Presence be said to be in any way ‘separate’ from the universe (that is, the sum total of all that is) for the notion of separateness denotes divisibility whereas this Presence is indivisible. All in all, it is a mature concept of deity.
