Mark A. Short, in his podcast The Builders of the Mystic Circle, explores the powerful concept of recognizing oneself as the primary cause in shaping their reality. Through the idea of the 'relative first cause,' Short discusses how our inherent ability to create and manifest can shape the world around us. He emphasizes the significance of understanding that our thoughts, intentions, and actions are the foundational elements that form our life experiences. Also, he talks about the crucial difference between primary and secondary causes and how they influence our daily lives. By practising Mental Science, taking control of decision-making, and focusing on our vision, Short illustrates that we are not mere spectators in life but the playwright, director, and lead actor. Finally, he reaffirms the principle that if you strongly desire something and hold that vision consistently, the resources and opportunities to achieve it will come your way, which he refers to as the Law of Supply.
