Mangal and Chandra, lords of a kendra (1st, 4th, 7th or 10th house, Vishnu's seat) and a trikona (1st, 5th or 9th, Lakshmi's), are joined: a Raja yoga. Mangal brings rise through land, engineering, the uniformed services and bold enterprise; Chandra, through public life, care, food, travel and people's goodwill. It gives most in their dashas and sub-periods.
