A quiet mind is a still mind. A still mind is an untroubled mind. An untroubled mind is a peaceful mind. A peaceful mind is a happy mind.
Quieten your thoughts.
A mind that is free of thought is free from delusion. It is no longer bothered by empty words of concept, opinion or perception, it is free to experience the bliss of unobscured absolute awareness — the very truth of being itself that is always ever-present.
