No, not what you think. What you believe, yes. Those are two different things to me. Thoughts are instinctual and irrational, often operating in bursts that can just run away with you. There are times, for example, when I feel myself judging another person for how they choose to present themselves and then follow that with reason and understanding. I've always liked the example that goes, "Your first thought is what you were taught. Your second thought is who you are." I think that's a good way to distinguish between thoughts and beliefs.
