Book excerpt: Leys are as elusive as beams of starlight. They are everywhere, you just can't see them. They may be compared to the hidden knowledge of a secret tradition. On public display and freely available to those in the know. Invisible and unsuspected by those who aren't. Thus the ancient wisdom at the basis of leys is encoded within the land for future generations to discover anew, if they possess the vision. London's leys can lead you to magical places, to the soul of the city and to an understanding of the hidden unity which connects our ancient sacred sites to each other and also links our spiritual dimensions to theirs. To our ancestors these locations were places of the gods, places of healing, places of power, places of vision initiation, inspiration and revelation. They still are.
