The heart of the path is quite easy. There's no need to explain anything at length. Let go of love and hate and let things be. That's all that I do in my own practice.
Regarding this Dhamma, it is not something that we can simply talk about or take another's word for it. We need to develop meditation so that the understanding arises clearly within oneself. It is not the case that merely by listening to another's explanation our defilements will disappear. When we gain some understanding we need to chew on it again so that we see it for ourselves with certainty: paccattam.
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.
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.
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.
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!
Of course there are dozens of meditation techniques, but it all comes down to this - just let it all be. Step over here where it is cool, out of the battle. Why not give it a try?
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.
If you want to understand suffering you must look into the situation at hand. The teachings say that wherever a problem arises it must be settled right there. Where suffering lies is right where non-suffering will arise, it ceases at the place where it arises. If suffering arises you must contemplate right there, you don't have to run away. You should settle the issue right there. One who runs away from suffering out of fear is the most foolish person of all. He will simply increases his stupidity endlessly.
Looking for peace is like looking for a turtle with a mustache: You won't be able to find it. But when your heart is ready, peace will come looking for you.
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.
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.
