Any message heard in the stillness and nothingness of the inner Self is a thought. Doesn’t mean it’s not enjoyable. Doesn’t mean it’s bad.
But messages can come through the mind in the form of a thought. Angels communicate through the mind in the form of thoughts.
All thoughts and messages are trying to describe what you already are which is indescribable, beyond birth and death and beyond words.
The mind can’t find what you already are.
Wisdom is knowing who you are through experience. There are many ways to experience who you are. One way is through Shuniya - pure nothingness.
Every voice you hear inside is a thought. Understanding that thoughts aren’t you is a key. It’s a question of, “Do I want to identify with this thought?” Maybe yes, maybe no. But always know it’s a thought and not who you truly are.
