But there is also the life of the spirit, and the life of the spirit is the analogue, on a higher turn of the spiral, of the animal's life. The progression is from animal eternity into time, into the strictly human world of memory and anticipation; and from time, if one chooses to go on, into the world of spiritual eternity, into the divine Ground. The life of the spirit is life exclusively in the present, never in the past or future; life here, now, not life looked forward to or recollected.
