All pre-Abrahamic cultures understood the tremendous importance of remaining closely connected to the past if the present was to be invested with any spiritually significant meaning. They also understood that the most personally relevant and accessible portal to the empowering wisdom and goodness of the past was through their own direct ancestors, those who shared their particular bloodline and DNA. It was for this reason that all traditional cultures engaged in what is often called ancestor worship (pitri-puja). There is no pre-Abrahamic culture on Earth that did not honor its ancestors in one form or another. This is a very important spiritual practice and tradition that used to be practiced universally by families in the ancient past. The process of ancestor worship now needs to be revived in the modern world if we are to not lose our sacred connection with our own cultural-spiritual heritage. Ancestor worship must become a regular practice again.
