The Presentist View
Today is a product of yesterday is it not? Without the actions of yesterday, there would be no today. Stands to reason then, that although yesterday has passed, it has relevancy mainly in helping you to understand how things exist today.
Why then are people afraid to look at the equation of the present? Looking at the past doesn’t mean you are living in the past or stuck in the past. The memory acts as parentheses encasing the variables, the factors that equate to your present existence. Know that equation is expansive, lengthening based on your decisions/actions in the present. Those decision/actions may be blind or informed...all depends on your courage to look at your history, the histories of others, and the level of your awareness.
Creation cannot exist without first the process of creation.
