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.
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.
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 sink deeply into the mind so that whatever we do, the mind has always goodness within it. All the ways of making merit are aiming at this. Goodness lies in the right view that is established in the mind. Then we don't have to celebrate it or let anybody know about it, simply let the mind have firm confidence in the goodness and keep going 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.
If you let go a little you will have a little happiness. If you let go a lot you will have a lot of happiness. If you let go completely you will be free.
I am like a tree in a forest. Birds come to the tree, they sit on its branches and eat its fruits. To the birds, the fruit may be sweet or sour or whatever. The birds say sweet or they say sour, but from the tree's point of view, this is just the chattering of birds.
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.
To observe and watch one's own mind is something really interesting. The untrained mind will run and follow its old habit patterns. Because it has not been trained and taught, it will get lost in all kinds of stories and issues. Therefore we have to train our mind. The meditation practice in Buddhism is all about training one's own mind.
One day some people came to the master and asked: How can you be happy in a world of such impermanence, where you cannot protect your loved ones from harm, illness or death? The master held up a glass and said: Someone gave me this glass; It holds my water admirably and it glistens in the sunlight. I touch it and it rings! One day the wind may blow it off the shelf, or my elbow may knock it from the table. I know this glass is already broken, so I enjoy it - incredibly.
