Just know what is happening in your mind - not happy or sad about it, not attached. If you suffer see it, know it, and be empty. It's like a letter - you have to open it before you can know what's in it.
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.
If we want to really see the Buddha, we should observe his virtuous qualities. Whatever he taught, we should practise it. Only bowing to him is not enough. We need to renounce, give up, stop, so that we may see the Buddha.
You say that you are too busy to meditate. Do you have time to breathe? Meditation is your breath. Why do you have time to breathe but not to meditate? Breathing is something vital to peoples lives. If you see that Dhamma practice is vital to your life, then you will feel that breathing and practising the Dhamma are equally important.
People go through life blindly, ignoring death like revellers at a party feasting on fine foods. They ignore that later they will have to go to the toilet, so they do not bother to find out where there is one. When nature finally calls, they have no idea where to go and are in a mess.
We have limited time in our life, therefore we should try to teach ourselves, not to teach others. We should conquer ourselves, rather than conquer others. Whether coming or going, standing, sitting or lying down, our mind should be focused in this way. If we practise like this and develop mindfulness continuously, wisdom arises quickly and this is a fast way of practice.
When we conquer ourselves, then everything will be conquered: oneself, others, and all the sense objects as well, coming in by way of the eyes, ears, nose, tongue and body -- it will all get conquered like this.
We say that to 'give up all evil and to develop the good' is the heart of the Buddha's teaching. If we only make merit but have not stopped doing bad things, then we will never have a day of completion. It is like an overturned bowl which is left outside in the rain. Even if the water is falling right on it, it only touches the outside and not the inside. In this way the bowl will never get full.
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.
Once you understand non-self, then the burden of life is gone. You'll be at peace with the world. When we see beyond self, we no longer cling to happiness and we can truly be happy. Learn to let go without struggle, simply let go, to be just as you are - no holding on, no attachment, free.
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.
Know and watch your heart. It's pure but emotions come to colour it. So let your mind be like a tightly woven net to catch emotions and feelings that come, and investigate them before you react.
The Dhamma has to be found by looking into your own heart and seeing that which is true and that which is not, that which is balanced and that which is not balanced.
