One can experience this by feeling the atmosphere of different places. Sitting upon the rocks of the mountains one often feels the vibrations of the one who has been sitting there before. Sitting in a forest, in a wilderness, one can feel what has been the history of that place. It may be that there was a city, that there was a house, that people lived there, and now it has turned into a wilderness. One begins to feel the history of the whole place; it communicates with one.
