Rudra Yoga (रूद्र योग)
The Rudra Yoga is considered a powerful Raj Yoga (“royal yoga“, “royal union”, also known as Classical Yoga in Astrology). This Raj yoga gives spiritual distinction along with material growth.
Those who are born with this yoga are equivalent to Royals or pre-eminent individual who is greatest in importance or degree or significance or achievement
1. This yoga occurs with the association of Jupiter and mercury. Mercury should be in conjunction with Jupiter or in aspect by Jupiter. Mercury should be in 1st, 5th, 7th or 9th from Jupiter.
(1st is conjunction, 7th is opposite, 5th and 9th is trine)
This yoga is evident in Mahatma Gandhi’s horoscope were Mercury is in ascendant and Jupiter is in seventh house. So mercury is in aspect with Jupiter.
2. The house in which owner of the ninth house (Dharma Sthan) is placed; the Navanshesh of that particular house should be either in fourth or fifth house to materialize this Yoga.
