According to Vedic astrology, the placement of Sun in the 4th house for Aquarius lagna results in some unique astrological predictions. However, since Sun is in an enemy sign state, it may not have a strong influence on the native's life.
Sun is the natural karaka or significator of the 1st (self) and 10th (career) houses. As a result, when placed in the 4th house, which represents home and property matters among other things, the individual's focus would be directed towards their career advancement and self-interests. The native may feel more ambitious and driven to succeed in their chosen field.
Additionally, Sun is also lord of the 7th house (marriage and partnerships). Hence, this placement could signify a sense of responsibility towards maintaining healthy relationships with their significant others. But at the same time, since Sun denotes power and authority, there could be ego clashes with partners that may pose as a challenge.
The aspect of Sun on the 10th house indicates that it will take care of its natural karaka house i.e., career-related matters. This position can result in opportunities for promotion or recognition at work. The individual might also gain recognition from authorities or superiors for their hard work.
However, being placed in an enemy sign could cause some hindrances as well. It may affect the health of one's mother or father as well as impact domestic happiness. The individual may feel dissatisfied with their current living situation or struggle to find comfort within their own home.
It is advised that they pay special attention to family matters during this period while taking care not to neglect their professional aspirations altogether.
In addition to these predictions, it should be noted that each person’s natal chart acts differently due to various combinations of planets and signs along with other factors such as aspects and yogas present in them.
To conclude, individuals born under Aquarius ascendant should expect a focus on their career and self-interests during the time of Sun’s placement in the 4th house. They may also experience some challenges regarding family matters, but with proper attention and balance, they will be able to overcome these difficulties. The impact of planets varies based on their relative strength, planetary alignment, and other combinations present in birth charts. Vedic astrology is a fascinating tool that provides insights into one's personality and helps an individual navigate challenging situations by predicting future events.
