It would make sense that someone would initially say that the mind can be found in the brain. Upon further reflection, however, one will see the error in this assessment. Still don’t believe me? Ask yourself some questions: what color, shape, and form is your mind? Where do your thoughts comes from and where do they “live”? If you don’t hold onto your thoughts, do they stay somewhere or do they magically dissolve?
Delia Quigley in this recent Care 2 article discusses the difference between the brain and the mind and how in recognizing the answers to the above questions ultimately trains you for concentration. Using Ashtanga Yoga as a basis for her claim, Quigley explains how sitting in meditation for 15-30 minutes a sitting helps when it comes to developing the concentration needed to deepen your spiritual practice.
The path described by Ashtanga Yoga, the eight-limbed path, includes concentration (dharana) as the sixth limb and occurs only after you have been able to establish a single pointed focus on an object, word, or breath. After sitting in meditation for 15-30 minutes, you should begin to feel your body getting lighter and more relaxed. In the back of your mind, you may be semiconscious of your body and your surroundings or you may have no awareness of them whatsoever. You can concentrate on the OM mantra, or the even flow of your breath. It is not unusual to experience a feeling of great happiness while in this state of concentration; but be aware that this happiness is not the same as pleasure that arises from sensual delight.
