Q1 Though you're a socially comfortable person, you still clam up around people you perceive to have a high status level. This is an opportunity for you to work on yourself. What is it exactly you would have to know about yourself to be comfortable that you were on the same level?

In the above passage, why did the author use the past tense 'were' in the that-clause, like "that you were on the same level"? Does she mean to say "You have to remember that you and those high-status people were on the same level before you forgot it."?

Q2 Ask me no reason why I love you; for though Love uses Reason for his physician, he admits him not for his counselor.

What does this passage mean in simpler terms? Besides, what do the pronouns 'his, he, him, his' represent?
1. It's not a true past tense; it's referring to a hypothetical or supposed situation, similar to "What would you do if you were rich?".

2. "his" = "Love's", "he" = Love, "him" = Reason, "his" = "Love's".

The way I read it, it is saying that people use (or try to use) reason to "cure" themselves of love, but not to advise them in matters of love.
Thank you very much for your clear answer, GPY.
I understand.
