I have a theory about what causes depression, based on logic and my observations over the years.
I have long seen that people who do not express their Mars energy, aka their anger and ambition, tend to become depressed. This makes sense because Mars (raw male energy), by it’s nature is overt. If it is repressed it can do nothing but pervert. Most commonly this manifests as depression.
Mars likes to go and do and win and conquer. When people are depressed they tend to feel lethargic and want to sleep all day. You see the correlation. Some depression is anger, turned in on the self.
Saturn in combination with the Moon or the IC, in the natal chart or by transit has long been associated with depression, for good reason. In 40 years of astrology, I’ve not seen even one person with a Saturn Moon contact, natally or by transit that has not dealt with depression on some level. But this seems to be of a different flavor than Mars-based depression… it’s cold.
I realize some depression has a physiological basis. I am talking about depression that might be treated without drugs. It seems if you can isolate the cause it would be easier to address the situation.
Here’s more on this:
Do you tend to be depressed? Can you define your suffering? What’s the astrology?
