Mercury, also known as Budh, is considered a highly important planet in Vedic astrology. Its placement in the 4th house for Libra Lagna, while being in friend sign state, can have significant effects on one's life and personality.
In this placement, Mercury is the lord of the 9th and 12th houses, which indicates that it takes care of these houses. The 9th house represents higher education, spirituality, and long-distance travel. Therefore, individuals with this placement may benefit from good opportunities for pursuing higher education abroad or may develop an interest in spiritual practices such as meditation and yoga.
The 12th house is associated with foreign travel, hidden enemies, losses, and expenses. As Mercury rules over this house as well, individuals with this placement may face unexpected losses or expenses related to foreign travel or may have hidden enemies at work. They need to be careful about their expenses and try to avoid taking impulsive decisions while making financial commitments.
As Mercury has natural karaka of the 4th and the 10th house, its placement in the 4th house helps take care of its own karaka houses. The 4th house represents home, motherland, mental peace while the 10th house represents career and profession.
Individuals blessed with this placement are likely to be skilled communicators who can express their thoughts and emotions without difficulty within their family members thereby promoting harmony and happiness amongst them. There might be a possibility of owning multiple homes for them too.
In terms of career growth & profession path: Mercury’s aspect on the 10th House could indicate an increase in intellectual pursuits during their early career days. They might choose professions like teaching/consultancy that allows them scope for sharing their knowledge/experience; they may become successful writers/publishers too. At times they might come up with more innovative ideas than others but would need support from other planets for seeing it through.
As Mercury aspects the 10th house, it can bring success and recognition in their chosen profession only after continuous hard work and focus. Here, individuals must avoid taking shortcuts in their career path. They should attempt every task with sincerity of purpose rather than worrying about results far too much.
In conclusion, Mercury's placement in the 4th house for Libra Lagna can have a mixed influence on one's life. Although it provides favorable opportunities to grow personally and professionally while ensuring a harmonious home environment; under certain circumstances unexpected expenses or hidden enemies at work may impact their expenses & professional growth directly. Therefore people with this placement must remain vigilant towards making calculated decisions in personal as well as professional front without deviating from their path combining hard-work with determination thereby achieving ultimate success later in their lives.
