Planets are considered dignified when they are in the signs which they rule. The benefits of any ritual are enhanced when the ruling planet is transiting this sign. But it is not possible for a planet to be exalted and dignified at the same time, but it is possible for a planet to be exalted, with the Sun in the same sign which could dignify the planet. Conversely, it is possible for a planet to be dignified with the Sun in the sign that this planet is also exalted in.
Here is a list of the planets and what signs they are in during their dignity and fall…..
