Thanks for your answer. But i would like to add something. I guess it's not necessary to load those condenser with Elements for the single reason they are already full of elemental energy. All plants "contain" an element. For exemple, garlic contain the Fire element intensivly (the fire of mars). Water, itself is a kind of condenser. So, when you make a fluid condenser using water and garlic, you have already a water impregnated with the fire element. So, then, why should i load it with more Fire ? I guess it's already satureted with Fire. No need to increase it. Then, you load it with a desire. My question was : if i have a condenser related to Air, then, should i use the evaporation process or is it the same to use combustion ? ---------------------------------------------- Concerning what you said... if i take oil for example (a good natural condenser) and load it with a desire and let it evaporate... is it enough to activate this element ? I hope i'm not too boring. Thanks again for the time you spend to help all of us. Some of your writings have really help me.
