Holding on to beliefs limits our experience of life. That doesn’t mean that beliefs or ideas or thinking is a problem. It’s the stubborn attitude of having to have things be a particular way, grasping on to our beliefs and opinions, that causes the problems. Using your belief system this way creates a situation in which you choose to be blind instead of being able to see, to be deaf instead of being able to hear, to be dead rather than alive, asleep rather than awake.
As people who want to live a good, full, unrestricted, adventurous, real kind of life, there is concrete instruction we can follow: see what is. When you catch yourself grasping at beliefs or thoughts, just see what is. Without calling your belief right or wrong, acknowledge it. See it clearly without judgment and let it go. Come back to the present moment. From now until the moment of your death, you could do this.
