BaZi is commonly used for destiny analysis. In reality, BaZi has a much wider application. It can be a tool to help you know yourself better. Knowing your own BaZi can help you in the following ways.
BaZi can help you know your potentials by revealing your fate (缘) or affinity. In layman term, fate is simply chance or opportunity (机会). When a BaZi shows the presence of certain element, it indicates the presence of certain fate (or affinity). When this element is strong and favorable, the fate would be strong. A strong fate indicates better opportunity and hence better potential. For example, when a BaZi shows the presence of strong favorable wealth element, it indicates better wealth opportunity and hence better wealth potential.
BaZi can help you know your strengths and weaknesses by revealing your favorable and unfavorable potentials. Simply knowing your potentials is not good enough because not all potentials are favorable. It is important to know which potentials are favorable (喜) and which potentials are unfavorable (忌). Only favorable potentials are true potentials. For example, when a BaZi indicates strong wealth potential but the element representing wealth potential is unfavorable, it indicates that the wealth potential may lead to financial difficulty and loss.
BaZi can help you know your risks in career, marriage, wealth, etc. Knowing your risks would make you more conscious in managing yourself through appropriate behaviors and precautionary actions. For example, when your BaZi show a strong weakening of a certain element. It indicates that things associate with this element may be at risk. When this element represents your Spouse Star, it indicates that you may have marriage risk.
BaZi can help you to know your destined path to success. For example, when your BaZi shows a strong Day Master, your destined path to success is via the route of talent or performance (i.e. via Eating God Star and/or Hurting Officer Star). This means your success begins with talent. It is through talent that you achieve wealth and power. People in this category include actors, sportmen, etc. People in this category often have to excel in a certain field in order to achieve success.
When your BaZi shows a weak Day Master, your destined path to success is different. Your route to success is via knowledge and cultivating support from noble people and friends (i.e. via Direct Resource Star and/or Indirect Resource Star). People with weak Day Master are better off leaverging the support of other people. People in this category include sales people, relationship managers, leaders, etc. People in this category achieve success through team effort.
