Let the soul banish all that disturbs; and let the body that envelops it be still, and all the fretting of the body, and all that surrounds it; let earth and sea and air be still; and heaven itself. And then feel the Spirit streaming, pouring, rushing into you from all sides, while you are quiet in this Peace.
Time is not a line but a dimension, like the dimensions of space. If you can bend space you bend time also, and if you knew enough and could move faster than light, you could travel backward in time and exist in two places at once.
