I came across this statement:

Saturn represents Mothers, Guardians.
Is Moon Primary Mother and Saturn Secondary Mother, perhaps Grandmother?

And a question: what house is the house of Grandmother and yes grandchildren?


Saturn is the setter of limits and boundaries and thus represents the mother.

I would point you to the work of Bruno and Louise Huber for a more detailed explanation.


Moon is pure perception of world, how we relate to it. Thus its ruled by Cancer , thereby going naturally to 4th house of home and mother nourishment. Moon is quite feminine if its not influenced by malefic planets.

Saturn represents old people, for example grandfather or grandmother, who teaches us the lessons in life.
Saturn's natural home is 10th and 11th house and gets exalted in 7th house of Libra, means directional strength.
