Just keep coming home to yourself, you are the one who you've been waiting for.
Everything that happens is God's will. When you realize that, you're home free.
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.
Once the mind is met with understanding, it can always find its way home.
