Kabbalistic teaching: Three Inaudible Sounds "Three sounds are inaudible to the human ear: the sound of the snake shedding its skin, the sound of a soul leaving the body at death, and the sound of birthing. Where do these sounds go? They travel to the canyons where they encrypt themselves in the earth. The sound of your voice in the canyon awakens them from dormancy and evokes their powers. However, to awaken the sound of the snake shedding its skin, you must tap wood to stone. You hear these sounds as 'echos' but know that they are three sounds coming right back to you in the garb of your own voice or drumming, to empower you with shedding your old patterns, to aid you in surrendering to the uncertainty of your next step, and to guide you in birthing yourself anew." From the Zohar- Book of Splendor
