The Deeper Symbolism of Freemasonry from The Meaning of Masonry by Walter Leslie Wilmshurst.

“In symbolical language, the N. always signifies the place of imperfection and un-development; in olden times the bodies of suicides, reprobates and unbaptized children were always buried in the north or sunless side of a churchyard. The seat of the junior members of the Craft is allotted to the north, for, symbolically, it represents the condition of the spiritually unenlightened man; the novice in whom the spiritual light latent within him has not yet risen above the horizon of consciousness and dispersed the clouds of material interests and the impulses of the lower and merely sensual life.” [via]
