Woman: Well, I wouldn't say to keep out evil spirits. That sounds so superstitious. But I would say, it's a system of arranging all the objects around you at home or at work in such a way that they are in harmony and balance with nature in the way that feng shui teaches us to do then, therefore you are in harmony and balance and so is your life. Man: Now this is something that is very important in Asia. In fact, it's part of the architecture of buildings how the staircases go up, where buildings are aligned, what is your particular interest in it？ Woman: Yes, feng shui is huge in Asia, Taiwan, Singapore, Hong Kong. Even though it's officially frowned upon as a superstition, it's also huge here in the U. S. , no less than the Donald. Donald Trump, the billionaire real estate developer, doesn't make a move without it. He would no more start working on a building project without a feng shui master than he would without, if it was in L. A. , without.., a seismologist to tell him that the building would stay up in an earthquake. Umm. That's because.., these observations that amount to feng shui have developed over thousands of years and they work, as Donald Trump says. Man: How have you designed your house？ I mean, you say this is for how to change your life. Did you choose your home because of feng shui？ How did you set it out？ Woman: We didn't choose our home because of feng shui. We chose our home because it was what we could find at the time. I am lucky enough to have a great view out the window at the far end of my office. And I was going to put my desk facing out the window, and... uh... but I would've had my back to the door. Yet it's a bad idea to arrange your desk in this way according to feng shui, and actually anybody who comes into your office can surprise you. You're constantly off guard. So I turned my desk, so I still had the view at one hand and I had the door and the rest of the room at the other hand, and then I kind of put the other furniture in the office where it worked around that. Man: That is true. By the way, how did you develop your interest in feng shui？ Woman: I came at this topic pretty skeptically as a journalist, hard-bitten journalist that I was. I did a piece for the Los Angeles Times a few years ago on feng shui as real estate phenomena, because major deals rise or fall on good or bad feng shui. And then a few years later, I got a call from Villard Press, asking me to write a good, basic and accessible handbook on this topic. And I said, "Why, sure!" And, so then, I really got more deeply into it, started to study it. My friends would sort of lean in, look at me with one eyebrow up, and say, "Yeah, but do you believe this stuff？" And I would say, "Oh no! But don't quote me." Now, based on just simple things I've done and also lots and lots of people I talked to for the book, I'd have to say, it works and at the very least, it couldn't hurt. Man: When you walk into a building, are you able to sort of immediately sense whether it has good feng shui or not..., a good flow of the ch'i？ Woman: Yes, and so are you. Anytime you walk into any room, you get a feeling about whether you feel good about being there or not so good. You know, maybe your mood's a little peppier or maybe you're more relaxed..., whatever. It's just a positive reaction you get when you're in the midst of good feng shui Man: Well, I wish you good feng shui as you move through San Francisco here. Woman: Thank you.
