These days people don't search for the Truth. People study simply in order to find knowledge necessary to make a living, raise families and look after themselves, that's all. To them, being smart is more important than being wise!
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.
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.
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.
Do not be a bodhisattva, do not be an arahant, do not be anything at all. If you are a bodhisattva, you will suffer, if you are an arahant, you will suffer, if you are anything at all, you will suffer.
Dharma is in your mind, not in the forest. Don't believe others, just listen to your mind. You don't have to go anywhere else. Wisdom is in yourself, just like a sweet ripe mango is already in a young green one.
There are two kinds of suffering. There is the suffering you run away from, which follows you everywhere. And there is the suffering you face directly, and so become free.
The forest is peaceful, why aren’t you? You hold on to things causing your confusion. Let nature teach you. Hear the bird’s song then let go. If you know nature, you’ll know truth. If you know truth, you’ll know nature.
If you listen to the Dhamma teachings but don't practice you're like a ladle in a soup pot. The ladle is in the soup pot every day, but it doesn't know the taste of the soup. You must reflect and meditate.
With even a little intuitive wisdom we will be able to see clearly the ways of the world. We will come to understand that everything in the world is our teacher.
Do not be in a hurry or try to push your practice. If you become peaceful, then accept it,; if you don’t become peaceful, then accept that also. This is the nature of the mind. We must find our own practice and persevere.
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.
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.
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.
