These Aux stars are derived from the Yearly EB (earthly branch) in relation to Self EB or sector EB. In order to know whether it affects you, you need to plot your Bazi to check if it appears in your main chart. If you have this good or bad Aux stars the effects will happen during the year when it reappears, stronger during its EB month and also from the sector it resides.
Example: 2011 is EB-4 MAO Rabbit, The Dragon Virtue comes from the EB-11 XU Dog (NW-1), The Sun Star from EB-5 CHEN Dragon (SE-1), The Moon Star from EB-7 WU Horse (S-2) The White Tiger from EB-12 HAI Pig (NW-3), and many more
When you have these stars and want to activate them, you need to use XKDG Date Selection together with the Day's Flying Star and the correct timing. Sometimes you can't activate them due to the stars cyclic rhythm against your personal rhythm. This is Karma.
Like I said before, Destiny can be changed and by doing a lot of good deeds and to get rid of Aversion, Craving and Clinging, our bad energy will be weakened and the good ones enhanced. When the good Aux stars appear, good things may happen to you. Do not be greedy and chase for it. If it is yours, its yours when the right timing comes.
