The term 'Yoga' means union or association of two things. In Vedic Astrology 'Yoga' refers to association of planets, which yields specific results. The association of planets may primarily occur through (i) conjunction, (ii) mutual location in each other's sign, and (iii) by mutual aspect.
Among the 12 houses of the horoscope the 3rd, 6th, 8th and 12th house are regarded Triksthana (inauspicious). Among these the 6th, 8th and 12th houses are regarded Dushsthana (evil). The rest of the houses (i.e., 1st, 2nd, 4th, 5th, 7th 9th, 10th and 11th are regarded as good houses and creates house of fame astrology. Among these also kendras (1, 4, 7, 10) are called Vishnusthana (conferring happiness), and (1, 5, 9) are termed as Lakshmisthana (Conferring wealth. Thus Kendras and Trikonas are regarded as the most benefic houses.
The astrological classics describe the 'Yoga' (combination) of strong lords of benefic houses as Raja Yoga or Dhana Yoga, and mention the benefic results produced by these. The Yoga formed by the lords of malefic houses are called Duryoga (malefic) or Arishta Yoga (destructive).
As per Vedic astrology and for some Lagnas, a single planet becomes lord of both a Trikona and Kendra. For example, for Taurus Lagna, Saturn is lord of 9th and 10th house; for Leo Taurus Lagna, Saturn is lord of 9th and 10th house; for Leo Lagna, mars is the lord of 4th and 9th house; for Libra Lagna Saturn is the lord of 4th and 5th house; and for Aquarius Lagna, Venus is the lord of 4th and 9th house. Such a planet is called Yogakarka for the horoscope and produces very good result and fame in horoscope. When a yogakarka associates with other benefic planets, then better results are experienced by the native.
According to Laghu Parasari
meaning, "If the powerful lord of a Kendra is associated with a Trikona lord, it produces Raja yoga and gives auspicious results to the native."
The 10th house is the most powerful kendra, and the 9th house is the strongest Trikona. These houses relate to the most important aspects of life. The 9th house relates to Dharma (religion), Bhagya (Luck), etc. while the 10th house relates to Karma (profession), status, honour, etc. According to Phaladeepika (6.37):
meaning, "When there is fame in horoscope the lords of the 9th and the 10th house together occupy an auspicious house, it constitutes a Raja Yogaa. When the lords of other Kendra and Trikona houses are similarly placed, i.e., join together in an auspicious house, the resulting Yoga is called 'Sankha'. The Raj Yoga formed by the 9th (dharma) and 10th (Karma) lords is famous as Dharma-Karmadhipati Raja Yoga (DKRY).The native with strong DKRY in his horoscope attains high status, success and fame in his profession. The native born with Sankha Yoga is blessed with all types of comforts in life and fame in horoscope.
Uttarakalamrita further elucidates:
meaning, "The Raja Yoga formed by the following planetary combinations in a horoscope confers wealth and happiness to the native :
- The lords of the 9th and 10th house are in their own house.
- These lords are together in the 9th or 10th house.
- These exchange houses or Nakshatra.
- These aspect each other.
- These are with the lords of 1, 4, 5, 7 house.
- These are in 1, 4, 5, 7 house.
- But these two lords should not own the 8th or 11th house." It further adds.
- That is, "the three pairs of planets :
- The owners of the 9th and 10th houses from Lagna.
- The owners of the 9th and the 10th from the 9th house, and.
- Lords of the 9th and 10th house from the 10th house respectively give high, medium and small position to the native."
To produce the best result, the Yoga should be formed in a benefic house as fame astrology birth chart. Further, according to the ownership of planets for different Lagnas:
The Raja Yoga and is considered as best Yogas for fame life & gives best result for Virgo and Pisces Lagna, as the 9th lord is a benefic for the Lagna and the 10th lord is also the Lagna lord.

In Aries, Gemini, Leo, Libra, Scorpio and Aquarius Lagna, the 9th, 10th and Lagna lord are not friendly to one another. Hence, only mixed results are experienced by the natives.
