The present moment always feels to us the most vital, the most important, and the most essential. This is the nature of time. It is our nature. We will all experience great joy and great sadness as me move through life. This too is our nature. During periods of great sadness, it may be beneficial to remind ourselves that our lives are more than the moment of our experience at any given time.
This does not mean that what we are feeling is not real. Feelings are always real. What it means is that we have within us the power to perceive our loss, or grief, in the way of our choosing. We have the power to determine what our feelings mean.
