The results of the eighth house are analyzed on the basis of the position of the Moon in the horoscope. The eighth house aspects the second house in the horoscope. On the other hand, the second house aspects the sixth house and the sixth aspects the twelfth house. This way the eighth house reaches the sixth and the twelfth house through the second house.
Afflicted sixth or eighth house gives inauspicious results. This inauspiciousness affects the twelfth house as well. This is the reason why the 6,9, and the 12th house are also analyzed to determine accurate results.
The Moon is known to be the strongest when associated with the eighth house. Moon being in its own sign in the exalted position eliminates the negative effects of the twelfth house. However, if the other planet situated in the eighth house is the enemy of the planets in the second or eleventh house, the native has to suffer from great complications in life.
If the the planet in the eleventh house comes in the eighth or twelfth house, the native should not buy things related to the eleventh house. It can lead to health complications and loss of wealth. Saturn, Mars or Moon situated in this house give average results. Mercury in this house always give weak results. Mars remains bad in this house unless the Saturn is not in the second house.
Sun, Moon and Jupiter situated in the eighth house alone are not affected by the nature of this house. If either of them sits in the eighth house, the native gets to enjoy a good and pleasurable life. The justification for this fact can be explained in the following way:
The eighth house aspects the second house, the second house aspects the sixth house and lastly, the sixth house aspects the twelfth house. Thus, when either of the planet sits in the eighth house, it doesn't aspect the second house and the twelfth house. In this manner, the effect of the eighth house remains limited to it.
The malefic and the aggressive planets are the karakas of diseases in the eighth house. If the eighth house is weak, the sixth house weakens automatically. When the eighth house is the enemy of the second and the eleventh house, and the planet is the eighth house aspects the eleventh house, it attacks the eleventh house on the first fine opportunity.
The fourth house is often responsible for making the eighth house weak because the fourth, eighth and the twelfth house forms a trine aspect. The effects of the fourth house on the eighth house is through the second house. Thus, when the second house is emotty the effects of weak eighth house is limited to it.
