The doing of pure devotion to God, then, would be the culmination of a long intellectual process, comprising, broadly, the following stages:
- The unconscious entity: Examining and understanding prakrti, its evolutive nature, character and limitations.
- The conscious entity: Examining and understanding the body of man and its various organs and systems. Understanding especially the nature of the neural entities and the brain. Are they of the same essential characteristics as the external (unconscious) matter? Can the brain give rise to consciousness?
- The pure personality: Understanding the nature of purusa, its interface with the brain (and, through it, the body), the capabilities of purusa.
- The supreme pure personality: Relook at the programmed nature of the entities of the body such as the brain. Is their evolving out of prakrti possible in the absence of initiation and control by a superior conscious personality? Comparison with instances from the external world. The discovery of God, the supreme purusa.
- The revelation of the highest philosophy: The reason behind purusa becoming endowed with a (prakrti-made) body. Motivations of the supreme purusa. Consideration and full accommodation of the higher aspects of consciousness like compassion, grace and joy. Devotion to God, the supreme purusa.
God may be discovered solely through a (long and exhaustive) intellectual investigation without there being any need of any external revelation.
