Kendra and Trikona
Also known as: angular and trine houses
What are Kendra and Trikona houses?
Kendras are the angular houses (1, 4, 7, 10) and Trikonas the trine houses (1, 5, 9). Together they are the strongest, most auspicious houses of the chart.
The 1st house belongs to both groups. Kendras give strength and prominence; Trikonas bring fortune and dharma. An association between a Kendra lord and a Trikona lord, by conjunction, mutual aspect or exchange of signs, can form a Raja Yoga, and a single planet that rules both is called a Yogakaraka.
