If you take a relaxed walk beside a running stream, after a while you seem to flow as one with the stream. The hills on the opposite side of the bank also seem to move as one with you. Is the flow of the river and the flow of the self one? Is the self at one with the surrounds? As the self flows with the stream, the stream dissolves. And as one walks in harmony with the changing scenery of the mountains, the mountains dissolve. The self melts into the surrounds and the concepts of the mountains, stream and the self all fade away.
