When we say that the Buddha and the Enlightened Ones killed defilements, 11 it's not that they really killed them. If they had killed all defilements then we probably wouldn't have any! They didn't kill defilements; when they knew them for what they are, they let them go. Someone who's stupid will grab them, but the Enlightened Ones knew the defilements in their own minds as a poison, so they swept them out. They swept out the things which caused them to suffer, they didn't kill them. One who doesn't know this will see some things, such as happiness, as good, and then grab them, but the Buddha just knew them and simply brushed them away.
But when feeling arises for us we indulge in it, that is, the mind carries that happiness and unhappiness around. In fact they are two different things. The activities of mind, pleasant feeling, unpleasant feeling and so on, are mental impressions, they are the world. If the mind knows this it can equally do work involving happiness or unhappiness. Why? Because it knows the truth of these things. Someone who doesn't know them sees them as equal. If you cling to happiness it will be the birth-place of unhappiness later on, because happiness is unstable, it changes all the time. When happiness disappears, unhappiness arises.
The Buddha knew that because both happiness and unhappiness are unsatisfactory, they have the same value. When happiness arose he let it go. He had right practice, seeing that both these things have equal values and drawbacks. They come under the Law of Dhamma, that is, they are unstable and unsatisfactory. Once born, they die. When he saw this, right view arose, the right way of practice became clear. No matter what sort of feeling or thinking arose in his mind, he knew it as simply the continuous play of happiness and unhappiness. He didn't cling to them.
When the Buddha was newly enlightened he gave a sermon about indulgence in Pleasure and Indulgence in Pain. "Monks! Indulgence in Pleasure is the loose way, Indulgence in Pain is the tense way." These were the two things that disturbed his practice until the day he was enlightened, because at first he didn't let go of them. When he knew them, he let them go, and so was able to give his first sermon.
So we say that a meditator should not walk the way of happiness or unhappiness, rather he should know them. Knowing the truth of suffering, he will know the cause of suffering, the end of suffering and the way leading to the end of suffering. And the way out of suffering is meditation itself. To put it simply, we must be mindful.
Mindfulness is knowing, or presence of mind. Right now what are we thinking, what are we doing? What do we have with us right now? We observe like this, we are aware of how we are living. When we practice like this wisdom can arise. We consider and investigate at all times, in all postures. When a mental impression arises that we like to know it as such, we don't hold it to be anything substantial. It's just happiness. When unhappiness arises we know that it's Indulgence in Pain, it's not the path of a meditator.
This is what we call separating the mind from the feeling. If we are clever we don't attach, we leave things be. We become the 'one who knows'. The mind and feeling are just like oil and water; they are in the same bottle but they don't mix. Even if we are sick or in pain, we still know the feeling as feeling, the mind as mind. We know the painful or comfortable states but we don't identify with them. We stay only with peace: the peace beyond both comfort and pain.
You should understand it like this, because if there is no permanent self then there is no refuge. You must live like this, that is, without happiness and without unhappiness. You stay only with the knowing, you don't carry things around.
As long as we are still unenlightened all this may sound strange but it doesn't matter, we just set our goal in this direction. The mind is the mind. It meets happiness and unhappiness and we see them as merely that, there's nothing more to it. They are divided, not mixed. If they are all mixed up then we don't know them. It's like living in a house; the house and its occupant are related, but separate. If there is danger in our house we are distressed because we must protect it, but if the house catches fire we get out of it. If painful feeling arises we get out of it, just like that house. When it's full of fire and we know it, we come running out of it. They are separate things; the house is one thing, the occupant is the other.
We say that we separate mind and feeling in this way but in fact they are by nature already separate. Our realization is simply to know this natural separateness according to reality. When we say they are not separated it's because we're clinging to them through ignorance of the truth.
So the Buddha told us to meditate. This practice of meditation is very important. Merely to know with the intellect is not enough. The knowledge which arises from practice with a peaceful mind and the knowledge which comes from study are really far apart. The knowledge which comes from study is not real knowledge of our mind. The mind tries to hold onto and keep this knowledge. Why do we try to keep it? Just lose it! And then when it's lost we cry!
If we really know, then there's letting go, leaving things be. We know how things are and don't forget ourselves. If it happens that we are sick we don't get lost in that. Some people think, "This year I was sick the whole time, I couldn't meditate at all." These are the words of a really foolish person. Someone who's sick and dying should really be diligent in his practice. One may say he doesn't trust his body, and so he feels that he can't meditate. If we think like this then things are difficult. The Buddha didn't teach like that. He said that right here is the place to meditate. When we're sick or almost dying that's when we can really know and see reality.
Other people say they don't have the chance to meditate because they're too busy. Sometimes school teachers come to see me. They say they have many responsibilities so there's no time to meditate. I ask them, "When you're teaching do you have time to breathe?" They answer, "Yes." "So how can you have time to breathe if the work is so hectic and confusing? Here you are far from Dhamma."
Actually this practice is just about the mind and its feelings. It's not something that you have to run after or struggle for. Breathing continues while working. Nature takes care of the natural processes — all we have to do is try to be aware. Just to keep trying, going inwards to see clearly. Meditation is like this.
If we have that presence of mind then whatever work we do will be the very tool which enables us to know right and wrong continually. There's plenty of time to meditate, we just don't fully understand the practice, that's all. While sleeping we breathe, eating we breathe, don't we? Why don't we have time to meditate? Wherever we are we breathe. If we think like this then our life has as much value as our breath, wherever we are we have time.
All kinds of thinking are mental conditions, not conditions of body, so we need simply have presence of mind, then we will know right and wrong at all times. Standing, walking, sitting and lying, there's plenty of time. We just don't know how to use it properly. Please consider this.
We cannot run away from feeling, we must know it. Feeling is just feeling, happiness is just happiness, unhappiness is just unhappiness. They are simply that. So why should we cling to them? If the mind is clever, simply to hear this is enough to enable us to separate feeling from the mind.
If we investigate like this continuously the mind will find release, but it's not escaping through ignorance. The mind lets go, but it knows. It doesn't let go through stupidity, not because it doesn't want things to be the way they are. It lets go because it knows according to the truth. This is seeing nature, the reality that's all around us.
When we know this we are someone who's skilled with the mind, we are skilled with mental impressions. When we are skilled with mental impressions we are skilled with the world. This is to be a "Knower of the World." The Buddha was someone who clearly knew the world with all its difficulty. He knew the troublesome, and that which was not troublesome was right there. This world is so confusing, how is it that the Buddha was able to know it? Here we should understand that the Dhamma taught by the Buddha is not beyond our ability. In all postures we should have presence of mind and self-awareness — and when it's time to sit meditation we do that.
We sit in meditation to establish peacefulness and cultivate mental energy. We don't do it in order to play around at anything special. Insight meditation is sitting in samadhi itself. At some places they say, "Now we are going to sit in samadhi, after that we'll do insight meditation." Don't divide them like this! Tranquillity is the base which gives rise to wisdom; wisdom is the fruit of tranquillity. To say that now we are going to do calm meditation, later we'll do insight — you can't do that! You can only divide them in speech. Just like a knife, the blade is on one side, the back of the blade on the other. You can't divide them. If you pick up one side you get both sides. Tranquillity gives rise to wisdom like this.
Morality is the father and mother of Dhamma. In the beginning we must have morality. Morality is peace. This means that there are no wrong doings in body or speech. When we don't do wrong then we don't get agitated; when we don't become agitated then peace and collectedness arise within the mind. So we say that morality, concentration and wisdom are the path on which all the Noble Ones have walked to enlightenment.
They are all one. Morality is concentration, concentration is morality. Concentration is wisdom, wisdom is concentration. It's like a mango. When it's a flo
