"Do what Thou Wilt shall be the whole of the Law."

What would be the basic or fundamental meaning of the combination of the two trumps The Lovers and The Sun be? I know, for example both cards represent twins, I.e. Heru-Ra-Ha, so what would this mixture represent Thelemic wise? Also, what does the adding of the cards trump numbers represent exactly? For example what would the sum of these two cards (25) reflect?

Thank you for your help!
