WHOLENESS  AND DESTİNY

Past, present and future are wholly enfolded within oneness.

Thus, accepting destiny is being open to the reality beyond the limits of our senses' perception
 The whole universe is a complete, intelligent system. There is total order to all events; nothing is amiss.

From the perspective of this universal intelligence there are no 'time passages' such as those perceived by human minds. There is only one, eternal, undivided, universal moment that exists at once. 

So you cannot  change anything in the past . for further info    about  Wholeness and Destiny ( if you are interested )
