Eplerian philosophy is defined as: "Know who you are moment by moment." The purpose of this article is to show that the philosophy is based on scientific research, the relevance and implications, and how to apply the fundamental principles. This means knowing where you're thinking from and that's who you are. There are four locations you can think from: the head brain, the heart, the belly brain, and the mind. These are independent locations with no interconnection among them, and you can only think from one location at a time. The function of the head brain is to improve our financial and social lives daily by implementing the actions from the heart, the belly brain, and the mind. The feelings from the head brain include anger, stress from self-thinking, and pleasure from the addiction center. Application of the Eplerian philosophy is to bypass the head brain amygdala anger center, cingulate stress center, and the accumbens addiction center by thinking from the heart and the mind. The function of the heart is to keep itself healthy, and the feelings include kindness, empathy, gratitude, and giving. The function of the belly brain is risk-benefit management, and the feeling is fear. The function of the mind is creativity, and the feelings include total calmness and unconditional love. Thinking from the head is unhealthy, unproductive, and causes stress. Thinking from the belly brain keeps us grounded. Thinking from the heart and the mind is healthy and feels good. This is a new way of life for extraordinary living.
