The value of Dhamma isn’t to be found in books. Those are just the external appearances of Dhamma, they’re not the realization of Dhamma as a persona… - 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!

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.

Therefore the practice is like a key, the key of meditation. If we have the right key in our hand, no matter how tightly the lock is closed, when we take the key and turn it the lock falls open. If we have no key we can’t open the lock. We will never know what it is in the trunk.
