The 4th house and/or IC in astrology represents one’s roots, among other things. What does one’s roots really mean? The first thing that comes to my mind is lineage and ancestry.
For a plant’s or tree’s roots to take root, there must be a suitable soil, unless the plant is cultivated using hydroponics or aeroponics. That is to say, the root needs to be in an environment that encourages its growth.
Translating that into human terms, what environment is required before a person “takes roots” or settle down? In essence, it is having a real sense of belonging to a place, a community and family. If you have a sense of belonging, you are not likely to ever feel alone, lost or alienated. And that is a form of security that money can’t buy you.
