Cosmo Natal Report
Sun in the 2nd House by The Astro Codex :
Having the Sun in the house of material possessions and wealth, makes the natal chart owner be strongly connected to his belongings. Indeed, the Sun is responsible for one’s personal shining, and depending on where it is placed in the native’s chart, it makes the life departments ruled by the placement very important for him. Having some possessions brings to such a person pride, providing him security on which he can later build on. Especially in a man’s horoscope, the Sun in the 2nd house makes belongings really important for his self-esteem. In a woman’s chart, the effects are similar, although a little lighter. In addition, she might have the strong need to be proud of her father’s power and prosperity, as the Sun is representing the father in a chart. The Sun fixed in the Second house definitely helps with finances. A lot of money will channel through the native’s hands, as would a Jupiter or a Venus bring also. Nevertheless, the Sun is not only an attractor of wealth as the other two, but also a big spender. It radiates from the second house, tending to shine on other celestial bodies connected with aspects and located in other houses, empowering those houses’ issues. By observing with which planets the Sun is in aspect, the native can see which areas of life will both bring and demand flows of wealth, and a careful look at them can make them more careful in how they structure their expenses
