Physical bodies are mechanically created lunar vessels that we are magnetically pulled into by our psychological idiosyncrasies (ego). Usually, we are drawn into the same familial lineage, generation after generation, because of karma and deepening, strengthening bondage. In other words, most of us were our own ancestors. Therefore, the body dimly reflects our psychological history. Blood types are generally related to that lineage. However, your blood type is no different than your hair or eye color: it is only a superficial illusion. No blood type is superior or inferior to others. The masters do not have a special blood type. Masters arise from all races, colors, lineages, and both genders. Therefore, there is no physical characteristic of any kind that indicates superior or inferior spiritual development.
