We don't meditate to see heaven, but to end suffering.
If it isn't good, let it die. If it doesn't die, make it good.
You should think about your own death 3 times per day at the very least.
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.
Why are we born? We are born so that we will not have to be born again.
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.
