According to Sahl, if two houses have the same ruler, their meanings will be tightly connected if the planet is received. Otherwise, the connection will be mild.

Example: Jupiter for Pisces Ascendant: It rules both the 1st and 10th, which doesnt mean the person will be successful. However, if Jupiter is received by the lord of its sign, the linkage between 1st and 10th will be more evident.
