well it is part of it because everything as balance or harmony.

Yin/Yang Principle

One look at the magnificent coat of a Tiger reveals much as the black stripes that are overlaid against the backdrop of orange/rust coloring suggests a certain duality. In nature when there is such a significant contrast, this will often indicate a duplicity of meaning and/or purpose.

For the Tiger, this contrasting of patterns and colors suggests the Yin/Yang principle. Yin/Yang is the concept that all things in life are balanced via opposites and these opposites are equal halves of the whole. Female/Male, white/black, light/dark, are all examples of this polarity that is the basic foundation of this concept. Therefore, when looking at the Tiger Totem and its beautiful coat of mixed patterns and colors, it becomes evident that this is a creature being that possesses the balance of energies we may understand best as Yin/Yang.

As an animal totem, Tiger will walk beside the two-legged who is one of extremes in nature, feelings, and temperament. These are the individuals who run either hot or cold, full of passion or completely detached, there are very few periods of lukewarm for the Tiger Soul.

The challenge for these two-legged's is in finding the balance between extremes and understanding that the two halves are not contradictions of one another, but parts of an integrate Whole. By experiencing first one facet of life, feeling and being then the “opposite", the Tiger learns the importance of Balance.

Often times, the two legged with Tiger as an Animal Totem, will walk through the flames of hell and back several times during their lifetime. Many painful lessons will be encountered wherein he/she will expend themselves to the point of exhaustion and utter depletion, to then arise like the Phoenix out of their own ashes and begin a new cycle of growth and learning. Life for these souls is experienced whole heartedly and experiences which may discourage other less motivated individuals are frequently perceived by the Tiger individual as a challenge to be met head on and conquered.

When the two-legged with this awesome Animal Spirit comes to recognize the necessity of balance and harmony, the result is a wonderfully integrated human being. In so merging with the higher octave of Yin/Yang energy, the Tiger Soul embraces his/her inheritance of true Power and Integration.

The nature of yin–yangIn Taoist philosophy, shade and light (☯) yin and yang, arrives in the dàodéjīng (道德經) at Chapter 42.[9] It becomes sensible from an initial quiescence or emptiness (wuji, sometimes symbolized by an empty circle), and continues moving until quiescence is reached again. For instance, dropping a stone in a calm pool of water will simultaneously raise waves and lower troughs between them, and this alternation of high and low points in the water will radiate outward until the movement dissipates and the pool is calm once more. Yin and yang thus are always opposite and equal qualities. Further, whenever one quality reaches its peak, it will naturally begin to transform into the opposite quality: for example, grain that reaches its full height in summer (fully yang) will produce seeds and die back in winter (fully yin) in an endless cycle.

It is impossible to talk about yin or yang without some reference to the opposite, since yin and yang are bound together as parts of a mutual whole (i.e. you cannot have the back of a hand without the front). A way to illustrate this idea is to postulate the notion of a race with only men or only women; this race would disappear in a single generation. Yet, men and women together create new generations that allow the race they mutually create (and mutually come from) to survive. The interaction of the two gives birth to things.[10] Yin and yang transform each other: like an undertow in the ocean, every advance is complemented by a retreat, and every rise transforms into a fall. Thus, a seed will sprout from the earth and grow upwards towards the sky – an intrinsically yang movement. Then, when it reaches its full potential height, it will fall.

Religious and philosophical The Taijitu and concept of the Zhou period reach into family and gender relations. Yin is female and yang is male. They fit together as two parts of a whole.

Practitioners of Zen Yoga, a system of exercise created in 2007, see yin-yang as a flow.

The Taijitu is one of the oldest and best-known life symbols in the world, but few understand its full meaning. It represents one of the most fundamental and profound theories of ancient Taoist philosophy. At its heart are the two poles of existence, which are opposite but complementary. The light, white Yang moving up blends into the dark, black Yin moving down. Yin and Yang are dependent opposing forces that flow in a natural cycle, always seeking balance. Though they are opposing, they are not in opposition to one another. As part of the Tao, they are merely two aspects of a single reality. Each contains the seed of the other, which is why we see a black spot of Yin in the white Yang and vice versa. They do not merely replace each other but actually become each other through the constant flow of the universe. http://en.wikipedia.org/wiki/Yin_and_yang

so keep the balance and harmony become the circle.experience and enjoy.

"To destroy an undesirable rate of mental vibration, put into operation the Principle of Polarity and concentrate upon the opposite pole to that which you desire to suppress. Kill out the undesirable by changing its polarity." The Kybalion.

This is one of the most important of the Hermetic Formulas. It is based upon true scientific principles. We have shown you that a mental state and its opposite were merely the two poles of one thing, and that by Mental Transmutation the polarity might be reversed. This principle is known to modern psychologists, who apply it to the breaking up of undesirable habits by bidding their students concentrate upon the opposite quality. If you are possessed of Fear, do not waste time trying to "kill out" Fear, but instead cultivate the quality of Courage, and the Fear will disappear. Some writers have expressed this idea most forcibly by using the illustration of the dark room. You do not have to shovel out or sweep out the Darkness, but by merely opening the shutters and letting in the Light the Darkness has disappeared. To kill out a Negative quality, concentrate upon the Positive Pole of that same quality, and the vibrations will gradually change from Negative to Positive, until finally you will become polarized on the Positive pole instead of the Negative. The reverse is also true, as many have found out to their sorrow, when they have allowed themselves to vibrate too constantly on the Negative pole of things. By changing your polarity you may master your moods, change your mental states, remake your disposition, and build up character.

I think that this excerpt from http://www.kybalion.org/kybalion.php might be relevant.

Yin and Yang are opposite polarities of equal stature and complement each other to form a whole that is neutral or we could say in equilibrium. When this equilibrium is disturbed than we could say that we have too much yin or too little yang or too much yang and too little yin. In life yin and yang have to be balanced to have harmony. All of life dances to this tune of opposite polarities which in their normal and healthy state should be neutral.

In the law of attraction it is said that like attracts like and that is true but at the same time polarities or if you like yin and yang play a vital part. Asklepios gave a good answer on yin and yang as did White Tiger and below I give an example.

Lets imagine someone that is ill and wants to attract good health. Just the fact that they are ill tells us that they have lost their equilibrium. Their yin and yang is out of sync. Lets say this person wants to use the law of attraction to gain good health. We shall give this person a -negative polarity. They are going to focus on imagining themselves healthy, vibrant and full of life. Lets give these thoughts a +polarity. This will cause him to attract more of that which he/she needs (health) and bring him/her back to equilibrium which is a healthy state. By changing his/her vibration from too negative to neutral/normal by concentration on the positive=(like attracts like).

All in life want to be healthy and happy and that is our natural state (neutral, equilibrium) but when things go wrong we need the opposite of what we are experiancing and yet by concentrating on what we need we can attract it.

Yin and Yang and the Law Of Attractions, like attracts like, work on the same principle even thou most people get confused for they do not realise that by trying to attract what they like is the opposite of what they have.

You are right Bluebird you could say they are equal but unfortunately misunderstood by many.

It follows Ying/Yang principles. LOA is a connection of one form to an opposite form. A transition from inner world to outer world.

Law of Attraction is more like Yin & Yin or Yang & Yang

The Law of Attraction states, "LIKE attracts LIKE." Yin and Yang are OPPOSITES.
