Harihar Brahma Yoga is one of the important yogas mentioned in B. V. Raman's book titled: 300 Important combinations. This yoga provides all round happiness so it is a dream yoga to have in a horoscope. Term hari is used for Lord Vishnu, term har is used for Lord Shiva and term brahma is used for Lord Brahma. These yoga derives its name from the three principal male deities in hinduism.

     This yoga is quite complicated and not easy to understand. But three sets of planetary combinations are important for this yoga to form.

1. Jupiter, Mercury, Moon and Venus placed in eight house or twelfth house from second house lord results in this yoga.
2. Jupiter, Mercury and Moon in fourth house, eight house or ninth house from seventh house lord placement leads to this yoga being formed.
3. If Sun, Venus and Mars are placed in fourth house, tenth house or eleventh house from lord of ascendant.

     As one can imagine this is indeed very tough to understand. But fruits associated with this yoga are easy to understand. And that is what should be the basis to see if there is such a yoga in a native's chart or not.

     One born in this yoga would be an eminent scholar, truthful and have all the luxuries and pleasures life has to offer. He/She would be an eloquent speaker and helpful to others in need. He/She should be engaged in doing good work for the society.

     If someone has good knowledge and education, has good amount of money and beautiful house as well as is married to an attractive partner and goes routinely on romantic holidays than that means he/she has high chances of having Harihar Brahma Yoga in one way or other.

    Another important thing to note are the planets responsible for harihar brahma yoga to happen in horoscope. Jupiter and Mercury give good education. Moon gives wealth and good house. Sun gives knowledge. And finally Venus gives beautiful marriage partner and romance in life. People who have strong Jupiter, Mercury, Moon and Venus in horoscope may likely have good education, good house and abundant wealth as well as beautiful marriage partner.
