Patahara is an inward turning away from the turmoil of the world. Tarana means a focus, trying to hold on to the same sort at a stretch. Diana deepens into samadista - will you forget everything else? The purpose of meditation is to become absorbed in the object of meditation. If you eat too much and sleep too little, you can't have meditation. Thereis no experience of the world, no experience of your body. At one point, there's no experience of difference between meditator andMeditation.
