By thinking you cannot decide. It is not a question of deciding as a logical conclusion, it is a question of choiceless awareness. You need a mind without thoughts. In other words, you need a no-mind, just a pure silence, so you can see directly into things. And out of that clarity will come the choice on its own; you are not choosing. You will act just as a buddha acts. Your action will have beauty, your action will have truth, your action will have the fragrance of the divine. There is no need for you to choose.
