What is Meditation ?    

Meditation is an intensely personal and spiritual journey. Meditation is the route of knowing your self who you really are. To meditate is to turn in words, concentrate on inner self.

Meditation is not necessarily a religious practice, but because of its spiritual element it forms an integral part of most religions.

It has been used for thousand of years and is not as hard as you might be thinking. In fact after a little practice, it is down right simple.

Our greatest inspirations and truth come during time of QUIETNESS, STILLNESS, OPENNESS and REFLECTION - All components of meditation. The more we can clear our minds from all the cluster of the world, The more we can embrace real truth.

More About Meditation 

The basic idea generally associated with why people meditate is that during our day we are constantly subjected to sensory input and our minds are always active in the process of thinking. We read the newspaper, study books, write reports, engage in conversation, solve problems, etc etc. Typically, as we do these normal activities we engage in a constant mental commentary, sort of an inner "The Drama of Me." 

Usually people aren't fully aware of all the mental thought activity that we are constantly engaged in.   

Meditation allows all this activity to settle down, and often results in the mind becoming more peaceful, calm and focused. In essence, meditation allows the awareness to become rejuvenated'.

Meditation can be considered a technique, or practice. It usually involves concentrating on an object, such as a flower, a candle, a sound or word, or the breath. Over time, the number of random thoughts occurring diminishes. More importantly, your attachment to these thoughts, and your identification with them, progressively become less. The meditator may get caught up in a thought pattern, but once he/she becomes aware of this, attention is gently brought back to the object of concentration. Meditation can also be objectless, for example consisting of just sitting.

Experiences during meditation probably vary significantly from one individual to another, or at least if different techniques are involved. Relaxation, increased awareness, mental focus and clarity, and a sense of peace are the most common by-products of meditation. While much has been written about the benefits of meditation, the best attitude is not to have any expectations when practicing. Having a sense of expectation of (positive) results is likely to create unnecessary strain in the practice.

As well, since meditation involves becoming more aware and more sensitive to what is within you, facing unpleasant parts of oneself may well be part of meditation. Regardless of the experience, the meditator should try to be aware of the experience and of any attachment to it.
 
Failure to experience silence, peace of mind, mental clarity, bliss, or other promoted benefit of meditation is not in itself a sign of incorrect practice or that one can't concentrate properly or concentrate enough to be good at meditation. Whether one experiences peace or bliss is not what is important. What is generally considered important in meditation is that one is regular with their meditation -every day- and that one make a reasonable effort, but not strain, to remain with the object of concentration during the practice. With regular practice one inevitably acquires an increased understanding of and proficiency with the particular meditation technique.

Some people use the formal concentrative meditation as a preliminary step to practicing a mindfulness meditation during the day where one tries to maintain a calm but increased awareness of one's thoughts and actions during the day.
