It is not any organ of human body nor any tissue. If it is not any organ nor a tissue, then what it is? Is it related to human body, then to which part? Yes, it is related to human body but it is not related to any one part. It is related to whole human body. If it, is related to whole human body, then is it found inside human body or outside?

It is found inside human body and without it human body is dead. If any injury is done to it or it got injured then human body becomes diseased. But, when it is not injured and in perfect harmony, then body is in good health. 

• That is, curing its injury means returning human body from its diseased state back to health state. If, it is found inside human body, then what form does it have? 
• This vital force is first of all is a non-material thing. That is, it does not have a materialistic form. It is a spirit like non-material dynamic entity, force which runs whole human body. Without it human body cannot do its any single function. 
• In fact, if does not have vital force flowing through it, running through it, then human body is no more live it is dead.

It is found in both states of human body that is, health as well as in disease. The only state in which it is not found is death. Yes, it is absent in dead human body. 

• It is found only in living human body whether it is diseased or healthy. In diseased state, it is injured by morbific inimcal dynamic force but in healthy state of human body, it is as healthy, as human body itself it is. 
• And, curing injury of vital force back to its normal state means, returning human body from its diseased state back to its normal healthy state. Process of this returning back of human body from its diseased to health state is called cure.
