Our actions follow our thoughts.

We think some action and our body acts as a consequence. I want to move my finger which is a thought and my fingers move


Every thought,

Each thought we have in our mind


however____Transitory, which means for a momentum long one second or more______________,



causes muscular action,

we do have muscle action. Notice how , in my opinion, the muscle has a contraction and the action is the result. My hand's muscles contract and I can take a glass of water


which leaves its trace in that part of the physical organism which is most closely allied to it.

Its is a pronoun of which the reference is the antecedent: the contraction or action of the muscles

This action leaves a trace in that part of our body the closest

If I move my hand, just to give you an idea, the nerves and muscles of the wrist or the entire arm up to my shoulder have a trace of the contraction at the very end of my arm: my hand

I suggest you read our grammar book. Who aim to pass the GRE exam or similar exam CANNOT have any room of doubt on what is "its" in the sentence above or in general the difference between its or it's
