Book excerpt: Human life requires a myriad of tools to manifest its full potential. In Mastery of the True Self -- The discipline of Love through Sadhana, Aradhana, and Prabhupati, you will learn how discipline can support you in your journey of self-manifestation and self-realization as a unique human being. Discipline becomes a tool for self-evaluation, self-acceptance, and self-projection. A tool that can produce substantial, predictable, and repeatable changes in your physiological systems and in your consciousness. Learning to view yourselves under the lens of discipline helps you to unveil those things that keep you from being truly who you are and living a conscious, healthy, and happy life. Understanding discipline is a prelude to exploring Sadhana, Aradhana, and Prabupati -- the three facets of the path towards your highest Self. In this study, Sadhana Singh invites us to delve deeper into the reasons why the human being, already perfect in creation, needs discipline to experience the true Self and be able to live life freely, with love and happiness. In this perspective, we expose ourselves to constant training in order to make our expression more effective, our communication more sophisticated and our true essence express itself. Led by Sadhana Singh's writings and experience, we come to understand that developing ourselves is a form of spiritual training that provides us with a clear and complete perception of ourselves, of our own personal circumstantial reality, and of our Infinite Reality. Mastery of the True Self: The Disciple of Love through Sadhana, Aradhana, and Prabhupati explores bit by bit the elementary parts of the gradual process of building a solid foundation for igniting our awareness and manifesting our true highest Self.
