A white aura is the best aura……OSHO
A WHITE AND SMALL AURA IS VISIBLE JUST OVER YOUR HEAD. WHY IS NOT A COLORED ONE VISIBLE?
IT IS a colored one — but all the colors are there, hence it looks white. White is not colorless. White is the presence of all the colors together. White is the most colorful thing in the world — hence it looks white.
When a white ray passes through a prism it divides into seven colors. That's how a rainbow is created in the rainy season. Small particles of water hanging in the air function as prisms. White rays of sun enter through those hanging particles of water and are divided into seven colors. If you mix all the colors in the right proportions, you will create white. White is all the colors together.
I am not a Buddhist, I am not a Hindu, I am not a Christian, I am not a Jain, I am not a Mohammedan — and I am all. All colors together! Hence white is created. A white aura is the greatest possibility.
People have different auras: somebody has a black aura — black is the lowest possibility. Black is the absence of all colors. Hence, in all the mythologies we paint the Devil as black — that is the aura — we paint the Devil as black. Even negroes paint the Devil as black; they should paint the Devil as white, but they paint the Devil as black.
Black means the absence of all colors — absence of everything. Black is negative. Black is just nihilistic. Black means simply negativity. Black is death. That's why death is also painted black. And when you mourn for a person, you use black dress. White is the opposite polarity of black: black is the absence of all colors; white is the presence of all colors. White is an invisible rainbow.
Go on watching your own face in the mirror. Next time you stand before your mirror, don't be bothered too much with your physiological shape — try to see the aura. In the beginning it will not be visible, but if you go on working, within three months you will be able to see a subtle aura surrounding your face in the mirror. And that will be greatly indicative and helpful for your growth, because it will show the color where you are. If it is black, then much has to be done. If it is grey, then you are just in the middle of your growth; half the journey is over, half has yet to be travelled.
You ask: "Why is not a colored one visible?" — because all the colors are there it cannot be a colored one. A colored one means simply one color. And you will be surprised: if you ask the physicists, who know color well, what it is, you will be surprised. If you are using a red dress, that simply means the red color is reflected back, is given back to the world. Your dress absorbs all other colors; only the red color it doesn't absorb but reflects back, shares with the existence, it gives it back. It renounces red — that's why it is red.
This seems paradoxical: red dress is not red! It renounces red; that's why it looks red — people looking at you see it red because the red ray is going back and falls on their eyes and they see it as red. A black dress absorbs all; it doesn't give back anything. It simply absorbs all — the black is miserly, it doesn't share. It is a sort of spiritual constipation. It simply takes in and never gives out.
White simply reflects everything back, gives everything back. Hence, in India white became the color of renunciation. White means nothing is absorbed; all the rays are returned back to the existence — with thanks, with gratitude. When all the rays fall on your eyes, it looks white. When one ray falls on your eye — red, blue, green — then it is colorful.
A white aura is the best aura.
