根据短文理解,选择正确答案。

    Our spiritual intelligence quotient(精神智商), or SQ, helps us understand ourselves, and live fuller, happier lives.

    Though we're all born with SQ, most of us don't even realize that we have it. Fortunately, you don't have to sign up for classes to learn how to improve your SQ. Here are some simple steps that can lead you to this new level of understanding.

    Sit Quietly. The process of developing spiritual intelligence begins with solitude(独处) and silence. To tune in to your spirit, you have to turn down the volume(强度) in your busy, noisy, complicated life and force yourself to do nothing at all. Start small by creating islands for silence in your day. In the car, instead of listening to the music, use the time to think. At work, shut the door to your office between meetings, take a few breaths and let them out very, very slowly. Enjoy the stillness in your home after the kids are finally in bed.

    Step Outside. For many people, nature sets their spirit free. Go outside to watch a beautiful sunset. If you are walking with the dog, take the time to admire flowers in bloom; follow the flight of a bird and watch clouds float overhead.

    Ask Questions of Yourself. Ask open-ended questions, such as ‘What am I Feeling? What are my choices? Where am I heading?'

    But don't expect an answer to arrive through some supernatural forms of e-mail. ‘Rarely do I get an immediate answer to my question,' says Reverend Joan Carter, a Presbyterian minister in Sausalito, California. ‘But later that day I suddenly find myself thinking about a problem in a perspective(角度) I never considered before.'

    Trust Your Spirit. While most of us rely on gut(本能的) feeling to realize danger, spiritual intelligence pushes us, not away from, but towards some action that will lead to a greater good.
