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.
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.
Where does rain come from? It comes from all the dirty water that evaporates from the earth, like urine and the water you throw out after washing your feet. Isn't it wonderful how the sky can take that dirty water and change it into pure, clean water? Your mind can do the same with your defilements if you let it.
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.
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.
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.
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.
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.
