Perhaps ultimately, spiritual simply means experiencing wholeness and interconnectedness directly, a seeing that individuality and the totality are interwoven, that nothing is separate or extraneous. If you see in this way, then everything becomes spiritual in its deepest sense. Doing science is spiritual. So is washing the dishes.
Jon Kabat-ZinnBuckminster Fuller himself was fond of stating that what seems to be happening at the moment is never the full story of what is really going on. He liked to point out that for the honey bee, it is the honey that is important. But the bee is at the same time nature's vehicle for carrying out cross-pollination of the flowers. Interconnectedness is a fundamental principle of nature. Nothing is isolated. Each event connects with others.
Jon Kabat-ZinnFrom the perspective of meditation, every state is a special state, every moment a special moment.
