Ruchaka Yog is formed by Mars in a horoscope and it is considered as one of the 5 yogas which are called Panch MahaPurusha Yogas in Vedic astrology where the other 4 yogas of this class are Hamsa Yog, Malavya Yog, Bhadra Yog and Shasha Yog. According to the prevalent definition of Ruchaka Yog in Vedic astrology, when Mars is placed in 1st, 4th, 7th or 10th house from Ascendant or Moon in one of the three signs namely Aries, Scorpio or Capricorn, Ruchaka Yog is said to be formed in the horoscope. This yog can bless the native under its influence with courage, bravery, energy, logic and the ability to take right initiative at right time as all these qualities are possessed by Mars. Apart from these qualities, Ruchaka Yog can also bless the native with great name, fame and success by virtue of his bravery and courage.
Analyzing the definition of Ruchaka Yog which says that presence of Mars in any one of the above mentioned 3 signs in any one of the above mentioned 4 houses leads to the formation of this Yog in a horoscope, we can find out that every 12th person on average, has this yog in his horoscope. There are only 12 houses and 12 signs in a horoscope and the total number of combinations of presence of Mars in these 12 houses and 12 signs will be 144 as Mars can be present in 12 different signs in each of the houses which results in a total of 144 placements. Moving further, there are three combinations of Mars in 1st house which can make Ruchaka Yog which are, Mars in 1st house in Aries, Scorpio or Capricorn and similarly there are three combinations of Mars in 4th, 7th and 10th house which can make Ruchaka Yog and the total of these combinations comes out to be 12 which is one twelfth of 144 and hence every 12th person on average should be having Ruchaka Yog in his horoscope.
Every yog among Panch MahaPurusha Yogas is comparatively rare and it is not found in so many horoscopes as suggested by the prevalent definition of Ruchaka Yog. Therefore there should be more conditions which should be met in order to confirm the formation of Ruchaka Yog in a horoscope. To start with, Mars should be a benefic planet in a horoscope for the good effects of Ruchaka Yog to show in the horoscope as a malefic Mars will not form a Ruchaka Yog with good effects and on the contrary it can from a Kuja Dosha in three out of the four houses namely 1st, 4th and 7th house of the horoscope.
Mars is also known as a planet of conflicts, arguments, fights, battles and wars along with the positive qualities mentioned above and the negative qualities of Mars are very likely to show up first when Mars is malefic in a horoscope and at the same time it is placed in first, fourth, seventh or tenth house of a horoscope in Aries, Scorpio or Capricorn. Such a malefic placement of Mars can cause serious malefic effects and it can also lead to the formation of Kuja Dosha in the horoscope. It should be noted that Mars is very powerful when it is present in Aries, Scorpio or Capricorn and accordingly a malefic Mars present in any one of these three signs will make very strong defects due to its increased strength and the native under the influence of this malefic placement can become very argumentative, quarrelsome, criminal minded and in some extreme cases, the native under the strong influence of such a malefic placement can become notorious by virtue of illegal and immoral deeds done by him.
Hence it should be noted that there is a very fine line between a Ruchaka Yog, a Kuja Dosha or any other possible defect which can be formed in a horoscope by virtue of placement of Mars in any one of 1st, 4th, 7th or 10th house of a horoscope in Aries, Scorpio or Capricorn and this fine line is drawn by the functional nature of Mars in the horoscope. It means that a benefic Mars can form Ruchaka Yog in the horoscope whereas a Malefic Mars can form a Kuja Dosha or some other defect in the horoscope. Therefore the presence of Ruchaka Yog in a horoscope should be analyzed very carefully before making any predictions about this yog as it can be the exact opposite in some horoscopes.
Once the presence of Ruchaka Yog is confirmed in a horoscope, the next step is to determine the influence of other benefic or malefic planets on Mars as the influence of one or more than one benefic planet on Mars can significantly increase the benefic effects of Ruchaka Yog whereas the influence of one or more than one malefic planet on Mars can significantly reduce the benefic effects of Ruchaka Yog. In some extreme cases, the malefic influence of more than one malefic planets on Mars can completely nullify the benefic effects of Ruchaka Yog. The overall tone of the horoscope should also be analyzed properly as the presence of some serious defect like Sarpa Dosha in the horoscope can reduce the benefic effects of Ruchaka Yog in the horoscope whereas the presence of a benefic yog like Gaj Kesari Yog along with Ruchaka Yog can significantly increase the good effects of Ruchaka Yog.
Hence all the factors should be analyzed properly before predicting the presence of Ruchaka Yog in a horoscope and role of other benefic and malefic planets should also be properly analyzed. Ruchaka Yog in 1st house of a horoscope can bless the native with very good health, courage and professional success, Ruchaka Yog in 4th house of a horoscope can bless the native with great wealth, luxuries and comforts along with great successes, Ruchaka Yog in 7th house of a horoscope can bless the native with fame on international level and a very good married life among other things, and Ruchaka Yog in 10th house of a horoscope can bless the native with great professional success, name and fame among other things. The natives under the strong influence of this type of Ruchaka Yog can become some of the most renowned and famous warriors, army persons or defense experts of their times.
