The foundation of your being needs to change to raise your vibration.
We could say that raising your vibration is raising the foundation of your being, the foundation of your existence, the height from where you observe life.
Your foundation is set by your culture. Your culture also sets what you can hear and what you cannot.
What you cannot hear is what is higher than the level of your foundation.
You hear something… but by the time it becomes conscious, it is translated to the level of your culture. How? By hearing it in the mind, Plato’s Cave.
To the naked eye, you sound kind of stupid. A is said, and you hear B. Your actions will be based on B. And your results will also be based on B.
