To embrace change and the unknown is in the spirit of [the Japanese concept of] mono no aware. Mono no aware relates to harmony with the constantly changing universe and with the universal cycles of creation and destruction.
A mind that resides in the instant can encounter beauty in its greatest breadth, from instant to instant. Although the beauty of a painting is often completely experienced only upon first sight, this need not be the case. If the mind abides in the moment, and then lets that instant die, and rests fully in a new instant, that beauty can again be fully appreciated. . . . To understand mono no aware, we need to grasp that beauty and life exist in the instant. In mono no aware, we let the past dissolve, realizing that destruction is ultimately a postive act of creation.
