Anyway, here's the article excerpt.
Meditation is the art of mastering the mind through the development and strengthening of one’s awareness. Being that the subconscious mind is constantly dumping thoughts at random into the conscious mind and can hijack one’s consciousness and attention, it is critical that one develop their capacity to master their mind so that they can steer it in the direction they truly want.
As the barriers between the subconscious and conscious mind are gradually dissolved through the act of meditation, one progressively gains more and more of a leash over their consciousness, which in turn enables them to direct their will power more precisely into what they truly aim to accomplish with their life.
Being that our mind/brain is constantly in action in both our waking lives and dreaming lives, it is an organ of the body that is typically deprived of enough time to be rested and rejuvenated. In meditation, one seeks to relax the mind through putting one’s awareness and intention on stillness. In this state one allows themselves to stop their thoughts and worries and just be at peace for the meditations duration. If and when thoughts arise during meditation, it is the meditator’s mission to not engage in the thought, but to view it from a third person perspective without identifying with it.
Through the practice of this act, one gains more mastery over the subconscious mind and as well as a better perspective on their own undesirable mental programs that may be running like a feedback loop. As one progresses in meditation and the mind acquires more and more stillness, tension in the mind from over-active thinking is reduced and the grey matter of the brain becomes more soft and flexible. In turn the pineal gland which sits in the center of the right and left hemispheres of the brain is enabled to function with greater energetic receptivity and transmutation.
