The central premise of the book revolves around the idea that our predominant feelings and emotions shape our reality. Goddard argues that the key to manifesting our desires lies not only in visualizing them but also in feeling as though they have already been realized. Goddard emphasizes the importance of assuming the feeling of the wish fulfilled, meaning that individuals should immerse themselves emotionally in the experience of having already achieved their desires. He asserts that this emotional state, when sustained consistently, impresses upon the subconscious mind and sets in motion the forces necessary to bring those desires into physical reality. Furthermore, Goddard discusses the concept of mental imagery and its power to create and shape our experiences. He suggests that individuals should use their imagination to create vivid mental scenes that evoke the desired feelings, thereby attracting corresponding circumstances and events. "Feeling Is The Secret" serves as a practical guide for harnessing the creative power of the mind to transform one's life. It encourages readers to cultivate a sense of inner conviction and emotional congruence with their desires, ultimately leading to the manifestation of their dreams and aspirations.
