Aloha Susan,
They don't relate to your personal energy number(PEN) per say.
Each direction has a symbol, element, number, etc. associated with it at a Space Feng Shui level. The number "2" for instance is associated with the SW, and since SW represents romance, collaboration, motherhood, you'd place your activation for that area in pairs (2's) t reflect this.
Your PEN is associated with your 4 best direction at a personal feng shui level (think of it as a energy strata or level that you are activating, different than the space feng shui, or time feng shui levels). So think of them at this point as two different things.
P.S.
Not to confuse things, but others may be interested on a side note that one's PEN (unless you as a 5), is actually the number that represents your wisdom direction. So your friend who has a PEN of 4, will have SE (which is the direction in general space feng shui represented by the number four), as his/her growth direction.
Those with PEN's of 1 will have N as their Growth direction, 2's have SW, 3's have E as their growth direction, etc.
The 5's, following this would fall in the center on the chart on page 13, and so instead, share SW and NE with anther PEN.
Much Love, Shawn
