Dear John, Yes, twins will start out with the same "Heaven's map" but due to their individual experience plus:- 1. Feng Shui - in the future, should they be married or otherwise, they may not stay in the same home. Even if they stay in the same home, they may not sleep exactly at the same location (unless they continue to sleep on double decker beds all their life). 2. It is said that other attributes includes kindess, generosity and compassion differ from individuals. Please note that the above are not modern inventions with regards to Pillars of Destiny. The above are as mentioned earlier (above) are some of the `escape clauses' of Pillars of Destiny since it was devised. Warmest Regards, Cecil
