The second house is the house of resources, the material. And if the Sun is in the 2nd House, this indicates a practical person. The theme of accumulating resources is very important for the person, no matter what kind: material, financial, mental, physical, strengthening one's body, everything that he considers a resource.
Therefore, the person will invest a lot of effort to realize their material desires. And such a Sun in most cases gives satisfaction with their own benefits. The person very well feels that their well-being and earnings depend on them. He has a practical grip and effectiveness is important to him. He knows how to rejoice when he receives a reward for a job well done.
Such a person has good life energy. They love nature very much. Therefore, for many with the Sun in the 2nd house, it is important to have at least a piece of land, a country house, a dacha, to grow something with their own hands, to do something practical on this site.
There is often an interest or ability in various bodily practices.
The Sun, as the image of the father, can help with resources. And for the person himself, it is important in the future to provide for the family and himself.
With a damaged Sun, there may be problems with the heart (but you need to look at the sum of other houses of health, their relationship to each other).
