We use thinking as a tool, but the knowing that arises because of its use is above and beyond the process of thinking; it leads to our not being fool… - Ajahn Chah

This mind is an uncertain thing. This body is uncertain. Together they are impermanent. Together they are a source of suffering. Together they are devoid of self. These, the Buddha pointed out, are neither a being, nor a person, nor a self, nor a soul, nor us, nor they. They are merely elements: earth, water, fire and wind. Elements only!

Have you ever seen flowing water?... Have you ever seen still water?... If your mind is peaceful it will be just like still, flowing water. Have you ever seen still, flowing water? There! You’ve only ever seen flowing water and still water, haven’t you? But you’ve never seen still, flowing water. Right there, right where your thinking cannot take you, even though it’s peaceful you can develop wisdom. Your mind will be like flowing water, and yet it’s still. It’s almost as if it were still, and yet it’s flowing. So I call it “still, flowing water.” Wisdom can arise here.

So don't be in a hurry and try to push or rush your practice. Do your meditation gently and gradually step by step. In regard to peacefulness, if you want to become peaceful, then accept it; if you don't become peaceful, then accept that also. That's the nature of the mind. We must find our own practice and persistently keep at it.
