House 3—“Think Communicate, Communicate, Communicate”–When the Ruler of the 3rd House travels to another House and resides there, one will TALK about that subject a lot. Think of someone who talks, incessantly, about one thing. This may be the root. This is an easy House Ruler to understand as are most of the House Rulers traveling TO a House i.e. the first part of each “equation”. The second part of each equation is harder to wrap your mind around.
House 3 “Think Communicate, Communicate, Communicate”–When the Ruler of ANOTHER House travels to the 3rd House, that house will USE communication in service of it. I will give a few examples,as this may be hard to grasp. If the Ruler of House 5 travels to the 3rd House and resides there, the native will USE communication in his pursuit of fun( the domain of the 5th House). He may be a comedian.
If the Ruler of the 4th travels to the 3rd and resides there, the native will USE communication in his home.He will value a home with a lot of communication.
If the Ruler of the 6th is in the 3rd, the native will use Communication in his service. He may be the spokesman for a charity
If the Ruler of the 7th is in the 3rd, the native will USE Communication in his marriage. He will be the type of person who needs to discuss everything.
If the Ruler of the 8th is in the 3rd, the person will use Communication in his exploring all taboos. He may be a sex therapist, a sex educator, a Jungian therapist, an FBI Profiler who writes or lectures about his profession.
