It may be possible to teach a person the posture, the pose, the position of legs, feet or hands, neck, head or back, the style of breathing or its speed. But the meditation is a function of the inner man; it motivates deep subjective quiet, the employing on the mind and filling oneself with the light that emerges from the divine spark within. This is a discipline that no text-book can teach and no class can communicate.
