Apoklima houses

The Apoklima houses
Houses 3,6,9 and 12 are called the Apoklima or cadent houses.
Planets placed on these houses are considered weak or not very powerful.
Those houses correspond in meaning to the dual signs.
Among them, the 9 th house is the best since it is also a dharma house and planets placed here are strong and tend to bring good luck.
The 12 th house is considered the weakest one and planets placed here have difficulty to express their energy in the material concrete level, but they can be good for the spiritual advancement.
