Some say the #2 flying star is unlucky while others say it is lucky. From experience the #2 star can be one or the other depending on what combination and period it's in.
In the Period 7, the #2 generally brought sickness and ill health. Combine it with other bad luck number like the #5 and you get even more sickness and loss.
However, during that era, in combination with the #7 brought gains, but in the current 8 era, the 2/7 combination will cause damage and competition in business. The #2 in combination with the #3 it causes legal entanglements and stomach disorders.
However, the #2 in combination with the #8 brings great wealth in land, due to the Lucky 10 combination (2+8=10). Massive wealth can be created if one focuses their attention there more so in this current Period 8 era than ever. Keep an eye out on the increase in land and home prices if you haven't already. This dramatic increase should last up until the Period 9 era.
One can also acquire wealth by going into the health field, if you happen to be in a room with the #2 and the #6 or #8, since the #2 is interpreted as the "Heaven's Doctor." It also represents the door of which all things are born; the #2 can also represent fertility. So one must be very careful in such sectors since birth can be a blessing or a burden depending on one's readiness and state of mind.
A lot of medical related things come up when dealing with the #2 influence so if one can remain positive and take adequate care of one's health and spirit one can certainly reap the benefits. For instance, sometimes your sickness leads you to find a cure, which cures not only your physical state, but your emotional state as well, and in turn benefit the masses, hence increasing your karma and your finances.
Sometimes under duress, we give up our financial pursuit to find harmony with our surroundings, leading to greater spiritual enlightenment and leading us to like minded acquaintances and better opportunities. If you haven't noticed, healers can be either very rich or humble in their existence. It all depends on one's goal, preparation and fate.
It's most important to cure the negative numbers that combine themselves with the #2. Generally, in this era, one should use metal in most cases except for the #3 where wood is the prescribed cure and with the #7 one should use water.
