The experience of seeing a bright light in meditation is a high class of mystic occurrence and does not come to all. It is indeed a manifestation of God to the internal senses. It is not intended, however, to become a regular feature of the inner life because it is only a favourable sign or token of progress yet to come. Therefore he to whom this sign comes should not crave it as it happens only a few times in any one life, and in many cases does not happen at all even to advanced mystics. The important thing about it is the consciousness which comes with it, the sense of a sacred presence. The light itself, being an appearance, however wonderful, belongs to the realm of phenomena and like all other clairvoyant visions is not to be sought for its own sake.
