Mangal and Shani, 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; Shani, through long, patient work, large organisations, labour, land and service to many. It gives most in their dashas and sub-periods.
