"Those who have in any sense realised that God is around them, in them, and in everything, will be able to understand how a place or an object may become "sacred" by a slight objectivisation of this perennial universal Presence, so that those become able to sense Him who do not normally feel His omnipresence... This is the rationale of places of pilgrimage, of temporary retreats into seclusion; the man turns inward to seek the God within him, and is aided by the atmosphere created by thousands of others, who before him have sought the same in the same place....The effect produced will, of course, vary with the relative strengths of the vibrations... the laws of vibration are the same in the higher worlds as in the physical, and thought vibrations are the expression of real energies."
