Anxiety is a symptom of perceiving the world and our place in it as something they are not, which is a consequence of being disconnected from nature and reality. When we see things as they actually are rather than as our culture and evolution has programmed us to, justification for anxiety dissolves.
You will never die because you were never born, the universe only changes form. Meaning is created internally, not received externally. Life is not serious, but you can be sincere. All is connected, division is nothing more than a concept. When you hate another, you hate yourself. When you love another, you love yourself.
