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.
Educate your inner being in all aspects of life. Keep to the order you learned during your schooling. You did not begin all of a sudden to grasp the higher subjects; you started by learning the alphabet. The same applies to your soul. It is not good for it to strive toward exalted feats until it becomes familiar with the spiritual alphabet: humility and obedience. Let the whole of your life become a continuous prayer.
