You should know both the universal and the personal, the realm of forms and the freedom to not cling to them. The forms of the world have their place, but in another way, there is nothing there. To be free, we need to respect both of these truths.
The mind of one who practises doesn't run away anywhere, it stays right there. Good, evil, happiness and unhappiness, right and wrong arise, and he knows them all. The meditator simply knows them, they don't enter his mind. That is, he has no clinging. He is simply the experiencer.
When we sit in meditation and hear a sound, we think, 'Oh, that sound's bothering me.' If we see it like this, we suffer. But if we investigate a little deeper, we see that the sound is simply sound. If we understand like this, then there's nothing more to it. We leave it be. The sound is just sound, why should you go and grab it? You see that actually it was you who went out and disturbed the sound.
Peace is within oneself to be found in the same place as agitation and suffering. It is not found in a forest or on a hilltop, nor is it given by a teacher. Where you experience suffering, you can also find freedom from suffering. Trying to run away from suffering is actually to run toward it.
A good practice is to ask yourself very sincerely, 'Why was I born?' Ask yourself this question in the morning, in the afternoon, and at night…every day.
To define Buddhism without a lot of words and phrases, we can simply say, 'Don't cling or hold on to anything. Harmonize with actuality, with things as they are.'
Meditation is like a single log of wood. Insight and investigation are one end of the log; calm and concentration are the other end. If you lift up the whole log, both sides come up at once. Which is concentration and which is insight? Just this mind.
The ultimate truth is like the flavour of an apple which you can't see with the eye or hear with the ear. The only way to experience it is to put the teachings into practice. Once you taste it, you are no longer in any doubt about its flavour and you do not have to ask anyone else. The problem is solved.
Read yourself, not books. Truth isn't outside, that's only memory, not wisdom. Memory without wisdom is like an empty thermos bottle - if you don't fill it, it's useless.
Practicing meditation is just like breathing. While working we breathe, while sleeping we breathe, while sitting down we breathe... Why do we have time to breathe? Because we see the importance of the breath, we can always find time to breathe. In the same way, if we see the importance of meditation practice we will find the time to practice.
One man watches a river flow by. If he does not wish it to flow, to change ceaselessly in accord with its nature, he will suffer great pain. Another man understands that nature of the river is to change constantly, regardless of his likes and dislikes, and therefore he does not suffer. To know existence as this flow, empty of lasting pleasure, void of self, is to find that which is stable and free of suffering, to find true peace in the world.
