As children, we naturally reside in a primarily theta brain wave state. We're learning, assimilating, and creating our idea of reality on this physical plane. Naturally, we end up taking on the ideas and "truths" of those around us, especially those we depend upon and look up to (parents, caregivers, teachers).
Many of the beliefs our parents and caregivers held originated from their parents and their perception of their own childhood experiences. This isn't where the story has to end, and I'm not sharing this to say "our parents messed us up and that's it."
Unlearning who we believed ourselves to be, unlearning those "truths" and trading them for what we know deeply within our hearts right now. Many of the Universal Truths we already knew as intuitive children, but the world told us we were wrong.
