Kaahala-yoga
Kaahala-yoga is formed when there is a strong Lagnesha and the lords of the 4th and 9th houses are placed in mutual kendras. It makes a person independent, fearless, famous, a military commander or head of a local community, respected by authorities, generous, and happy in the second half of life.
