You’re in charge of your actions. You’re not simply a victim of fate or of the stars or of some other being acting through you. You’re the one who’s making the choices. That’s what gives you hope.
"In the five reflections, the reflection on karma is the one that gives hope. You realize that you’re in charge of your actions. You’re not simply a victim of fate or of the stars or of some other being acting through you. You’re the one who’s making the choices. That’s what gives you hope. But it’s hope coupled with heedfulness. You’ve got the power to do good with your actions, but also the power to cause harm. The principle of karma is a double-edged sword. If you’re not careful, you can use it to cut your own throat. This is why the Buddha recommends reflecting on the principle of karma as a way of inspiring heedfulness." ~ Thanissaro Bhikkhu "The Sublime Attitudes" (Meditations2)
