A teaching to guide us through the practice of prostration and the energy with which we should approach it: bowing down to Mother Earth, says Thay, touching her with the forehead, we should make ourselves as low as possible, to empty ourselves, surrender to her and accept anything that she would give us.
Note: Prostration can be done in many postures - from full body prostration on the earth, to simply feeling our body or feet on the earth and any posture suitable for our own body, the most important thing is to approach it with the energy as explained in this audio.
