Yogi Bhajan taught us that wearing all white clothing expands our auric radiance by at least one foot. That is a good thing. A strong aura gives us a strong and solid identity and projection, and negative influences are automatically filtered.
Wearing white is also an exercise in awareness, as it takes more consciousness and care to keep white clothes clean. Here is a taste of what Yogiji said about wearing white:
"We wear white because it's a simple scientific fact that every piece of matter or material has a foot and a half aura. Every animal has a three and a half foot aura. Every human has a nine foot aura. And if we wear the cotton and we wear the white, this color therapy gives us one extra foot of aura.
"So, I trust my students will behave right, but in case they behave like animals, they will still have a margin, an edge. And that is what it's all about. You have to wear a natural fiber and you have to wear white. It's a pure color therapy and it's called auric color therapy."
[From Beads of Truth, Spring 1981]
"We adopted this color because of our background and to support our development. We ask you to wear white so that you will reflect what is outside and go within yourself—that’s what white clothes can do for you.
"When you are totally dressed in white, the entire face reflects, and then it is very difficult to become intimate. Wearing white demands that the other person deal with you on a higher level, because that person has to concentrate himself in order to advance.
"The most difficult thing on this planet is to wear white top to bottom; but it is also the greatest therapy. If you really want to test yourself, live in a white room. What it does to you in one week will shock you. From one Sunday to another Sunday, you’ll be a different person without doing anything.
"Some people think we are laying a trip. We are not laying a trip on anyone. We wear yellow. We wear blue. We know these colors, and we know their reaction. We are not formal. Sit in your own living room with a yellow house turban on—and then a white house turban. You will find the difference. Don’t ask me. Colors create an uncontrollable action in your subconscious mind of inspiration, productivity and expansion. Colors have an effect on consciousness.
"We wanted to develop a very fast, progressive, spiritual and technical method of all the colors, so we have adopted the one color of the seven colors, which is white. To you, white is just one color, but to me it is the total balance of seven colors."
