The Toltec Mastery teachings encompass various principles and practices, but one central concept is the pursuit of personal freedom through self-awareness, mindfulness, and liberation from limiting beliefs and societal conditioning. These teachings emphasize living authentically, with integrity, and in harmony with the Universe. By understanding and embodying these agreements, as outlined in 'The Four Agreements' by Don Miguel Ruiz, we elevate our consciousness and cultivate a harmonious existence.
