Eckardt Tolle's book A New Earth has been all the rage its seems thanks to Oprah, but for good reason as its got some important reminders and insights about the ego, living in the present, stillness and connection with nature. He says that nature is a beautiful access point to inner stillness; flowers are messengers from another realm. Be like the lilies of the field, not anxious for the morrow. Don't name the tree, just be present with the perception.
Becoming conscious of our thoughts and attachments instead of getting so identified with them, is to be freer from them and to recognize that they are not our real selves. If you are trapped in mental noise that absorbs your attention you don't see the vitality of the world.
Coming to Our Senses by Jon Kabat Zinn is lovely in helping me remember to not miss the feast available each day. David Whyte, Midlife and the Beyond, says you could do well to read a poem a day; to stop and ponder the deep looking of a poem, which by the way his are great.
Gratitude, gratitude, gratitude.
