It is a common misconception that a spiritual seeker must have faith in a god or divine entity to achieve self-realization. When one understands the teachings of the Upanishads, enlightenment is possible here and now without the word "God." The Mandukya Upanishad is for those students who want to practice spirituality without resorting to unnecessary abstract concepts.
The Mandukya Upanishad provides a comprehensive map for the inward journey that shows the individual the way from the mundane to the eternal. It describes this state as the ultimate reality and the goal of human existence.
When one understands the teachings of the Upanishads, then one realizes that life itself is a sort of worship that can shine on the altar of infinity. --From Chapter 1, "Awakening"
