Please enjoy this short teaching to guide us through the energy with which we should approach our Touching the Earth practice:
"Bowing down to the earth," says Thay, "touching her with your forehead and your four limbs, you should make yourself as low as possible - emptying yourself, surrendering yourself completely in order to become water [...] and accept anything that she would give you."
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.
