Should it not that one needs to see the influence of the depositor of lord of houses you referred, where in it placed. Not only that the placement of the lord of such houses in Navamsa and the depositor of that
Navamsa where it is placed in Rasi
For instance if the 3rd lord is Mars and is placed in Leo Navamsa, then placement of Sun in Rasi and accordingly the its role in rasi needs to be studied
As far desire is concerned one needs to see the 5th house and the karmastana too. That is my view, but I stand corrected , if someone has contradictory view
