Aquarius is the 11th sign of the zodiac and is ruled by Saturn. Having Ketu placed in the 3rd house for Aquarius lagna can lead to a variety of astrological predictions. Let us examine each aspect Ketu is having on houses 5, 9, and 12.
Firstly, Ketu's aspect on the 5th house can indicate detachment from children or lack of interest in procreation. The intelligence and creativity of the native may suffer as well. There can be issues with education, which may cause trouble for those pursuing higher studies. However, if Yogas such as Amala Yoga, Kemadruma Yoga or Gaja Kesari yoga present in horoscope then it will increase the chances of getting benefited from this placement.
Secondly, Ketu's aspect on the 9th house reduces luck and fortune which can create obstacles in religious matters or spiritual pursuits. Luck does not seem to favor native in matters like pilgrimage visits, spiritual discourses by gurus/praacher or dharma related activities are likely to be less fruitful. Native may feel that all his efforts have gone in vain after taking few such initiatives.
Thirdly, Ketu's aspect on the 12th house means that some health problems may arise and expenses might also rise beyond expectations which causes economic difficulty along with stress & tension because there will be sudden unexpected payments coming up at intervals creating financial anxiety Lastly native could face unnecessary opposition from secret enemies who wish to harm them through malicious means this includes betrayal from friend circle too.
Despite these negative aspects of Ketu in conjunction with the third house for Aquarius lagna natives, there are some positives as well.
For instance, they may have spiritual inclinations or psychic abilities but only if certain yoga combinations support it such Budha Aditya yoga (Mercury & Sun conjunction) , Ruchaka Yoga ( Mars drejta ) etc. The detachment from their siblings can also be beneficial if they use it to focus on their own path and growth. The 3rd House of the horoscope is also known for communication skills. Aquarius natives with Ketu in this House have excellent communication skills, which they can use to express themselves creatively through writing or other mediums.
Moreover, one may experience sudden professional progress due to the harsh planet's presence in-house (given other favorable yogas), which naturally boosts one's social standing and financial position. One may also benefit from profiting through ventures initially started as hobbies or interest groups upon Ketu's influence.
In conclusion, having Ketu in the 3rd house for Aquarius lagna may bring about challenges regarding children, education, luck, health-related expenses and secret enemies but there are still positive aspects such as increased spirituality or creativity. Native can improve Aquarius native's lives by taking care of how they use their good traits while trying to mitigate the negative ones.
