Its instruction focuses on developing an awareness of the science of the human soul. The secrets of our mental and spiritual nature; and the many principles of our intellectual life and experience are brought into our conscious awareness. We learn that difficulties and obstacles placed in our way are a necessary means of developing the full potential good within us. The only way we can approach perfection is by honest and disciplined effort.
In one of the most profound lectures in all of Masonry, we learn that the quest for self and spiritual improvement is a journey of exploration, education, and discovery. Our goal is to become transformed as better men.
The arrival at the Middle Chamber is a symbol of transformation. One starts his journey in ignorance, and ends as a different person, strong, enlightened, in command of his passions and emotions, truly free for the first time, and ready to take command of his life.
When we are at this unique and sacred place in Masonry, we are prepared to know three kinds of truth: moral truth (to truly know what is right and wrong), intellectual truth (the knowledge of what is accurate and what is false) and, if we develop ourselves far enough, Divine truth, which is beyond human understanding. The Middle Chamber becomes a symbol of the soul, or spirit, for it is only there where we can receive Divine truth.
