The 2nd house represents your money matters, self-worth, possessions and your relationship with the material world.
However, it's not just about monetary value -- the 2nd house also influences your personal values and belief systems, what you like and what you don't like and the principles that help govern your everyday life. Taurus, the horoscope sign wrapped up in luxury and creature comforts, rules over the 2nd house.
Your birth chart is divided into 12 "houses" which govern specific areas of your life. At the time of your birth, each planet was located in a particular astrological sign and in one of the 12 houses.
