The mind, tipping back and forth, tween past and future, to what we saw or what we think we'll see. Tip it in either direction and we're abiding in our imagination, distracted from reality, from the here and now.
It's relatively rare that our present circumstances present conditions that warrant worry, anger, jealousy, fear, etc. Most often these emotions arise out of thinking about what has passed or has yet to come.
When we seek and find the fulcrum, that perfect point that gives rise to balance of mind, neither dwelling in the past nor future, it is here that we experience reality in its purest, most beautiful, worry free form.
We find it through the practice of mindfulness, by focusing our full awareness on the sensations of the mind and body. We first acquaint ourselves with our restless mind, catching then coaching it back to what's really happening here and now. It runs off, and again, we catch then coach it back to our side.
Through regular, repetitive practice, over time we touch that space between the tipping points, where thoughts fall away, and in their place...
...well, that's for you to find ; )
