The art of being lost is not a matter of merely getting lost, but rather being lost and enthusiastically surrendering to the unlimited potential of it and using it to your advantage. The shift from being lost to being found is a gradual one.
The way to encourage that shift is to first accept that you don't know how to get to the place you want to be and then opening fully to the place you are until the old goals fall away and you discover more soulful goals emerging. Then you are no longer lost, but you have benefited immensely from having been so.
The exerience of Oneness is not limited to just the great mystics of all the ages. Each one of us is invited to experience this Oneness and we can do so in all our endeavors. We can experience and utilize our Oneness when we are appreciating the beauty of nature, in our spiritual practice, in the creative process, and in our social action in the world. When we are feeling separate from our God source, we can find deep within us that knowing of Oneness to guide us back into the Light.
