I totally understand what you are saying, I think. You want your direct experience of the Dhamma to be pure,to be your direct experience not based on someone else's perception or their direct experience then translated for you. Is that right?
I sometimes think the same thing and I am very mindful of how other's ideas effect my own, but then I came to realize that my ideas are not really my own anyway.
So here is my advise:
Recieve all teachings with an open heart, attach to none.
