The placement of Sun in the 8th house for Capricorn ascendant individuals can have an impact on their life from various aspects. This placement is considered to be auspicious as Sun is in its mooltrikona state, which means it is in the sign where it has the most strength and potency.
Firstly, let's analyze the effect of Sun being lord of the 8th house. The 8th house represents transformations, secrets, mysteries, longevity, inheritance, debts and loans. The presence of Sun as its lord indicates that the individuals born under this ascendant would have a deep interest in occult sciences or mysticism. It also suggests that they may experience transformational events in their lives or have a fascination with death and rebirth.
However, as Sun is natural karaka for the 1st and 10th houses representing self and profession respectively, it will take care of these areas even when placed in the 8th house. So, this placement can also bring success in career or leadership positions due to their authoritative nature and strong willpower.
Moreover, Sun's aspect on the 2nd house can result in financial stability and growth through hard work, determination and perseverance. It also suggests that these individuals are likely to inherit property or assets from their family members or ancestors.
But as always there are some downsides to every astrological placement. As Sun signifies ego and self-importance, its presence in the transformative eighth house can create issues related to power struggle with friends/colleagues/family members or overconfidence leading to falls from grace if unchecked.
Additionally there may be some health issues related to reproductive organs like- infertility and other problems related to urinary tract. They may suffer from chronic illnesses such as diabetes if proper care isn't taken regarding food regimen & lifestyle choices.
In conclusion we could say that individuals with Capricorn ascendants having sun placed in their eighth house need to keep their ego in check &need to be practical and sensitive at the same time in matters related to family relation, finances, joint property or inheritance etc. Paying attention to health and diet would also help in staying healthy and energetic for the long haul.
