Some quotes from Ajahn Sumedho.
Learn how to trust and rest in this state of pure knowing: It is like this. It can't be any other way. You need mindfulness (sati) to keep remembering this state and returning to it. This stillness of the mind is non-critical, non-judgemental. It's an intuitive, direct knowing, it's not analytical. This is called nanadassana, or insight knowledge.
Discussing 'Transcendental Dependent Arising' (suffering --> faith --> gladness --> rapture --> calmness --> happiness --> concentration --> knowing and seeing things as they are --> disenchantment --> dispassion --> liberation --> destruction of the effluents): It begins with positive states like 'gladness' and 'happiness', so you would expect it to get better and better, but then it goes to ... disenchantment, or nibbida. It's like when you see some children playing on the sand, with buckets and spades, building sand castles and roads and bridges. I used to play like that when I was young! But then as you get older and you see small children playing in this way, you are no longer interested in it, you become disenchanted with it. And then dispassion arises, you can no longer get involved in the quarrelling and disputes among the children on the playground. You see society, people around you, getting upset and obsessed by such unimportant, trivial things.... That's how the arahant sees the world. And that's liberation.
In meditation we are breaking down the illusion that the mind is in the brain. Actually, the brain -- and the whole body -- is in the mind! The brain is more like a radio receiver. Each of us is a separate conscious entity in the universe. We all see the world from here. Consciousness is like light which makes things visible. Each of us is the centre of the universe, the centre of the mandala. That's why we are ultimately alone. Nobody can help you do this practice, it's only up to you.
If one is looking for perfection in a Buddhist teacher or in a Buddhist tradition, one will be greatly disillusioned by it. If one looks for perfection in anyone, or in the perfection of one's own body and the conditions of one's mind... it is not possible! One cannot force the mind to think only good thoughts, or to be always compassionate and kind, without giving rise to even an impulse of aversion or anger.
The mind is like a mirror -- it reflects. So the wise man knows the reflections as reflections, and not as self. Reflections do not harm the mirror at all. The mirror can reflect the filthiest conditions and not be dirtied by it. And the reflections change. They are not permanent.
And what is right speech? Abstaining from lying, from divisive speech, from abusive speech, & from idle chatter: This is called right speech.
