The twelve houses
3rd House
Also known as: Sahaja Bhava, house of courage
What does the 3rd house represent in astrology?
The 3rd house (Sahaja Bhava) governs courage, initiative, younger siblings, communication, skills and short journeys.
It is the house of self-effort — hands, writing, media, hobbies and the everyday boldness to act. Mars, the karaka of courage, is its natural significator.
As an Upachaya (growing) house, planets here — even natural malefics — tend to improve with time and effort, which is why a strong 3rd house is prized in charts of athletes, writers and entrepreneurs.
