Hello Dear @rawdoctor you cant imagine how happy i would be to write my thoughts on this topic. Half year ago i used crystals for increasing the vibratory field around my energy body. I use to save and send a high vibrational energy from higher dimensions in to those crystals. Certainly according to your date of birth person should choose his own crystal. Definetaly human who feels convinient with obsidian may look into parallel dimensions, without a doubt. You can do it with multiple different crystals. You are totally correct with the name of this post. Crystals may save lives. Also the only main difference in everyone evolution is the ability of a human being to pass through yours energetic body the high vibrational energy and also try to sustain it within you as much as possible even if its difficult in 3rd dimensional reality. Furthermore those crystals on your photo can help to achieve this goal and charge you energetic body and conscious like a battery with a high intensive energy. Great instrument to and very helpfull. Photos are amazing i would live in that place.
