We are living beings with histories unique to each of us. Among these experiences will be subjects of torture, as well as torturers, accidental deaths as well as intentional ones. Crippled through past life conditions, starvation, fatal illnesses and all the other experiences human are subject to. And not humans alone. Look at the way we treat the animals, particularly those we use for food. Castrastion, dehorning, working to exhaustion and all the rest. All these conditions leave scars upon the soul, and the etheric bodies that lie between the personality and the soul.
Then along come genetic scientists declaring that they have found this or that gene that controls this or that condition. But the reason for a condition may be various and many between different people. Let us consider the number of illnesses that affect the lungs alone. Cancer, the biggest fear of western people today, tuberculosis, pneumonia, whooping cough and on and on. Yet suddenly the geneticists tell us they have found the gene to prevent this or that.
Personally I feel that having learned the letters of a language does not mean that you are able to speak the language that uses that script. Let alone understand what is being said. But while we adopt the position that human bodies are machines then this alternative view will be completely ignored and even ridiculed.
