If there is a mooltrikona sign in the fourth house from the ascendant, its lord is called the most benefic planet (MBP). In case there is no mooltrikona sign in the fourth house, then the role of the most benefic planet is played by the lord of the second house containing the mooltrikona sign. In case there is no mooltrikona sign in the second house, then the role of the most benefic planet is played by the lord of the ninth house containing the mooltrikona sign. And if there is no mooltrikona sign in the ninth house, too, then the role of the most benefic planet is played by the lord of the third house containing the mooltrikona sign. For various ascendants the most benefic planets are as under:
