Sit back-to-back with your partner, supporting each other equally. Take deep, slow breaths. Relax into a common rhythm. Experiment with one partner exhaling as the other inhales, and vice versa. Paul and Marie Jerard also do a supine head-to-head variation of this, with the lower legs elevated on a folding chair (blankets are on the seats and a blanket may be under the head, depending on the natural tilt of the cervical spine). The knees and hips are set at 90 degrees and your crown chakra is about six inches away from your your partner's crown chakra.
