Quote paraphrased from their own literature:
"A lodge has 3 symbolic lesser lights--East, West, and South.
There is no light in the North."
(Why?)
Because "Solomon's Temple was placed so far north of the ecliptic that the sun and moon at their meridian height coulddart no rays into the northern part thereof."
Every Lodge is a representation of King Solomon's Temple.
What does North represent?
North represents ignorance, as study and spiritual examination are not possible in darkness.
The North, masonically speaking, is a Place of Darkness.
