Question: How can we feel that faith above reason influences us now and that it is leading us out of low states?

Answer: You do have knowledge, but go against it in the power of faith, contrary to your knowing. That is how you move forward.

If you are trying to unite hearts, it means that there is faith in them. Whenever there is a chance, you must re-choose the point of faith above reason and move from there.

Question: How can we act correctly above knowledge regarding the material world, and is it necessary to seek balance?

Answer: There is no need. Just cut yourself off from the material world whenever you can. Engage in spiritual things, and if necessary, return to the material.
