I believe my question was unclear, allow me to clarify what I meant.
Do aspects between planets take into consideration the signs of the two planets that are aspected with each other and the aspects and houses, or not?
For example, a moon in aries conjunct their mercury. Is it applying just the persons Mercury and not the sign weilding the Mercury or the aspects; in other words, is it just applying Mercury alone and not the sign its in or its aspects?
Or is it applying the sign the Mercury is weilded in and the aspects too?
Or lets say a moon is in aspect with ones midheaven. Would this mean the persons moon is receiving energy from the planet that rules midheaven as well as the sign the midheaven is in and aspects to it?
Or would it be simply applying the energy of midheavens ruling planet and not at all the sign the midheaven is in or its aspects?
