Education is one of the most important aspect in any body's life which helps in creating the overall personality of a person. Education is indirectly related to bringing success in one's life. It gives the person the ability to generate money and sustain his livelihood.
Houses Relevant to Education:
Education of a person is seen from the 2nd, 4th, 5th and 9th house. Why such houses? Well, 2nd house shows early childhood studies and development stages, 4th house shows your emotional sensitivity towards learning and grasping the content. 5th house is the main house of education that show if you'll at least pass high school education and go on the get a Bachelor degree. 9th house in a horoscope shows the higher education the post grade or grad degree like Masters and PhD.
Apart from this, combinations like Buddhaditya Yoga, Saraswati Yoga involving Sun, Mercury, Jupiter and Venus indicate prominence in education. Mars, Saturn, Rahu and Ketu indicate education of different dimension. All these are relevant with various combinations that allow variety of qualifications. If the 2nd and 5th house is afflicted, one is devoid of education. Jupiter remains the primary karaka for determining the ability to study and progress in education. How these combinations would impact your horoscope?
Malefic Planets in 2nd house:
If there are malefic planets present in the 2nd house like Rahu, Saturn or Mars then early childhood education would have been impossible to achieve if not difficult while it gives a native a harsh tongue and anger problems.
Having planets like Mercury, Venus, Sun and Jupiter or any of these four combination would make a person well versed in the Vedic or ancient scriptures, especially astrology. Malefic in the 4th house again makes it hard for a person to comprehend things while studying. Planets like Mars, Saturn, Rahu and Ketu gives very difficult time during high school. While planets like Sun and Jupiter gives lots of interest in spiritual and philosophical studies.If Venus and Mercury are placed in the 4th house while Sun and Saturn are placed in the 10th house then it gives interest in government and politics. Any planet in the 10th house aspects the 4th house, which greatly impacts the basic education of a person in terms of how easy or difficult it might be.
Now, if you have your basic B.A. and you're trying to go for your masters or PhD, then you must look at the condition of 9th house, and see who's the lord of the 9th house, where is it sitting, who is sitting in the 9th house and what planet are aspecting the 9th house. If Rahu and Saturn are sitting in the 9th house or aspecting the 9th house without any benefice aspect on it then it will either block or delay the post grad education until after mid 30's.
Ketu is also important, Ketu is a headless planet, which means it doesn't think, and having Ketu in the 5th & 9th house without the help of other planets will make a person have no interest in education but have more interest in research subject without formal schooling. Since 3rd house is directly opposite of the 9th house, any planet sitting there will also impact the higher education. If Saturn and Rahu are sitting in the 9th house but Jupiter is sitting in the 3rd house, will actually make a person pursue law field which is a post grad education. In a way Jupiter not only helps in archiving the higher education, but, having other planets there will change the course of study for the native.
