I have been practicing “Da Zuo” for a long time. It is good for mind healing and inside peace. I like show some tips I discovered:
Legs: The full lotus position with the feet placed sole upwards, on the thigh of the other leg, is recommended. This is the preferred posture of many practicing yogis or people capable of performing real magical feats that are produced by the mind’s power. However, I have always meditated sitting cross-legged with both feet on the floor. Also, I find that when I place a firm cushion under the buttocks, it helps to keep my back straight, and reduces the “pins and needles” effect.
If even this posture is difficult for you, you can sit on a straight- backed chair with both feet planted firmly on the floor. You will find if you examine old pictures of the Egyptians that they are shown seated in this way. And if even this is difficult, try lying down with your back straight and your hands by your sides. This position is also acceptable. The only drawback of such a position is that you will find yourself falling asleep! When assessing posture, always be comfortable. You cannot get into a state of relaxation when your physical body is uncomfortable.
Arms : Shoulders and arms should be relaxed. This improves circulation and helps to keep you awake. As for your hands, either rest them lightly on your knees, palm downwards, or hold them loosely on your lap with the fingers aligned.
Back: The back must be straight, held relaxed but upright. It is when the back is straight that energy can easily flow through. A straight back is also conducive to longer periods of meditation. I have found that it is only when I have succeeded in staying comfortably upright that I can really feel any mind relaxing and focusing more clearly. So make the effort to get it correct before proceeding.
Eyes: Keep you eyes lightly closed and cast downward. This enables you to shut out distractions. It is not advisable to keep your eyes too tightly closed. It is said that closing the eyes causes drowsiness but I suggest that you do whatever makes you comfortable.
Mouth: Your entire mouth and jaw should be relaxed and comfortably
loose. Teeth are kept slightly apart, with lips kept lightly together.
Tong tie: The tongue should be slightly touching the upper palate behind the teeth. This stops the saliva from flowing, and enables you to concentrate for longer periods.
Head: This should be naturally balanced. Do not tilt the head too far forward or backward. Hold it in such a position that your gaze can be directed naturally toward the floor in front of you. When the head position is held too high or too low, wandering thoughts can hinder concentration.
