The fact is that we so often choose to view thoughts as flighty things -- once thought, we wish them away as though they never were. No harm in this, we reason, it's just a thought. Yet perhaps this is not the wisest approach we can take.

Believing that thoughts themselves have no real and actual affect upon us, we can so very easily allow even the most negative thought to go unchecked and unchallenged. After all, we reason, it's only a thought, it doesn't really matter.

It's as if we believe that thoughts are wispy and insubstantial things, with no real existence, capable of dissipating and disappearing into the ether once we have experienced them. Perhaps it's because our thoughts are such private things that it's easy to imagine them as insubstantial and intangible.

This of course can only happen if we hold the belief that the mind and the body are quite separate, disparate entities, each with its own distinct domain, operating independently of each other.

The truth, of course, is that mind and body are indeed interconnected, with each affecting the other. Each thought we think has its consequence. And those consequences can indeed have a tremendous affect, not only on our mind and our feelings, but also on our body. Negative or positive, thoughts do indeed have a very real affect upon us.

Let me illustrate this with a simple little exercise that nicely demonstrates the tangible effects of thought - and the interconnectedness and inseparability of mind and body. To do this, I am going to ask you to use your imagination.

Imagine yourself walking over to your refrigerator. As you open the door, there's the soft sound of the seal being broken and perhaps the feeling of cold air escaping. Now, imagine that there's a lemon in there and imagine yourself reaching in and taking that lemon out. Maybe you can sense its cold feel, as you carry it over to a board where you can slice it.

Now imagine yourself taking a knife and slicing the lemon in half, lengthways. Perhaps you can see the white, pithy part and some seeds too, as juice trickles out. Now cut the lemon again, so that you have a quarter, a nice wedge. Lift it up and hold it under your nose. Perhaps you can almost smell the pungent lemon aroma. Now imagine yourself sinking your teeth into that lemon wedge. Really squeeze it so that the juice spurts into your mouth and onto your tongue, maybe some of the juice even trickles down your lips onto your chin.

Exercise over.

If you really did imagine sinking your teeth into that lemon and squeezing the juice into your mouth then a couple of things will probably have happened: The muscles of your jaw will have automatically tightened as you did so and there will have been an increase of saliva in your mouth.

Now, we know that the flow of saliva is not under the control of the conscious mind; it's controlled by the unconscious mind. It simply cannot be willed.

What's happened, of course, is that the subconscious mind cannot distinguish between real and imaginary. For it, a thought is treated as a reality and an imagined lemon is as real as an actual lemon. The simple act of thinking about sinking your teeth into a lemon is enough to produce the exact same physical affect as if you had really done so.

A thought which existed in the mind has had a tangible effect on the body.

In India, the very real nature of thought has been recognised for milleniums. There, astrologers make horoscopes for the birth of a thought or a question, in order to better understand it. It is a practice that has survived thousands of years. This branch of astrology is called horary astrology. For these astrologers, a thought is something very real and tangible.

The fact is that the thoughts we think affect us on many levels, including the physical. This means that the thoughts we have and the things we tell ourselves, about ourselves, in the privacy of our own mind affect not only how we feel, but what we become. After all, if thoughts have physical consequences, then they can make us ill or well.

When you find yourself thinking negatively, or experiencing a period of difficulty in your approach to the world, when you find yourself thinking thoughts such as: 'I'll probably come down with...'; 'I'll never be able to..'; 'I'll probably only fail...'; 'I don't really deserve...'; immediately replace the thought with a positive statement or affirmation. And repeat it at least 10 times. Make a habit of this and you can change your reality.

Here are some examples you can use, and of course you can create your own as you go along. Select one and use it for at least a month.

'I am becoming balanced and whole in body, mind and spirit'

'The past is over now and I am free to move on with my life'

'I am alive, healthy and free'

Be sure to repeat your positive statement 10 times when you awaken in the morning and just before sleeping at night. Repeat it any time you find yourself engaging in negative thinking. Remember, practice is the key here. Simple persistence produces real results!
