Recover lost knowledge
To set out to recover lost knowledge assumes knowledge exists in the first place and that it is possible for it to be lost. If you take the view awareness evolves from nothing, then you sense it is never lost. Wisdom is not the same as knowledge.
Compassion for the self means you are patient on any quest. It means you are ready to understand that all teachings originate from the source, from one master. This being manifests in different forms. You are in the process of recovering lost teachings of master within yourself. Why deny they exist?
What would you say if you were that master, if everyone was that master, with the potential to access infinite knowing from within? How would gaining such insight change how you perceive ths world and others? What are you already doing every moment? What are you progressively remembering?
In other words, you are not the physical body. You are not the illusory beliefs that keep you where you are. Mindsets that guide you actually lead you away from core consciousness that is you. To remember how to access inner realms of being is truly liberating. It is reconnecting to soulfulness.
