Regular cross-legged practice can improve the flexibility of legs, ankles and hips and make them soft. Meditation cross-legged on the bed (or sofa) for 20 to 30 minutes before going to bed or getting up early every day can reduce and slow down the blood circulation in the lower body, thus increasing the blood circulation in the upper body, especially in the chest and brain. Most importantly, this posture is conducive to sitting posture, so that the respiratory system is not blocked and breathing is smooth.
