So, how do you get back to heaven? To begin with, just notice the thoughts that take you away from it. You don't have to believe everything your thoughts tell you. Just become familiar with the particular thoughts you use to deprive yourself of happiness. It may seem strange at first to get to know yourself in this way, but becoming familiar with your stressful thoughts will show you the way home to everything you need.
The basics teachings of Buddha are about understanding what we are, who we are, why we are. When we begin to realize what we are, who we are, why we are, then we begin to realize what we are not, who we are not, why we are not. We begin to realize that we don’t have basic, substantial, solid, fundamental ground that we can exert anymore. We begin to realize that our ideas of security and our concept of freedom have been purely phantom experiences.
Do not think that enlightenment is going to make you special, it's not. If you feel special in any way, then enlightenment has not occurred. I meet a lot of people who think they are enlightened and awake simply because they have had a very moving spiritual experience. They wear their enlightenment on their sleeve like a badge of honor. They sit among friends and talk about how awake they are while sipping coffee at a cafe. The funny thing about enlightenment is that when it is authentic, there is no one to claim it. Enlightenment is very ordinary; it is nothing special. Rather than making you more special, it is going to make you less special. It plants you right in the center of a wonderful humility and innocence. Everyone else may or may not call you enlightened, but when you are enlightened the whole notion of enlightenment and someone who is enlightened is a big joke. I use the word enlightenment all the time; not to point you toward it but to point you beyond it. Do not get stuck in enlightenment.
