Sufi's have a saying: "The Sufi is the son of time present"

Rumi, the great poet and teacher of Sufism, declares: "Past and future veil God from our sight; burn up both of them with fire"

Meister Eckhart, the thirteenth-century spiritual teacher, summed it all up beautifully: "Time is what keeps the light from reaching us. There is no greater obstacle to God than time."
