We are all interconnected, not just with our human world, but with the universe. It, too is characterized as an intrinsic part of life. It is further understood that in order to improve one's life, one needs to understand and accept this fact of life, and that the effort one makes at avoiding this fact of life is at the root of neurosis. In other words, denying anxiety is denying life itself. Our peculiar position of being mortal and being aware of it is a major source of anxiety, but is also what makes our lives, and the choices we make, meaningful.
Time becomes important only when there is only so much of it.
Doing the right thing and loving someone only have meaning when you don't have an eternity to work with. As Sartre put it, our existences precede our essences . Yet only by acknowledging our lives as more a matter of movement than substance do we stand a chance at authentic being. Suffering is due to attachment . We might say that at least much of the suffering we experience comes out of ourselves, out of our desire to make pleasure, happiness, and love last forever and to make pain, distress, and grief disappear from life altogether.
