The Yogakarka | A Planet with an exceptional strength

In Vedic Astrology, a "Yogakaraka" refers to a single planet that gains exceptional strength and promises significant beneficial results in a horoscope.

Rule of formation:

A planet that is the lord of both a Kendra (quadrant: 1st, 4th, 7th, 10th houses) and a Trikona (trine: 1st, 5th, 9th houses). The relationship between the lords of Kendras and Trikonas is known as Yoga, which gives exceptionally auspicious results.

If Rahu or Ketu occupy a Kendra or a Trikona and are related to a Trikona lord (if in a Kendra) or a Kendra lord (if in a Trikona), they can become Yoga karakas.

Planets as Yogakarakas for Specific Ascendants (Lagnas):

Mars: Becomes a Yoga karaka for Cancer and Leo ascendants. For Cancer ascendant, Mars owns the 5th and 10th house and for Leo ascendant, it owns 4th and 9th house.

Saturn: Becomes a Yoga karaka for Libra and Taurus ascendants. For Libra ascendant, Saturn owns the 4th and 5th house and for Taurus ascendants, it owns 9th and 10th house.

Venus: Becomes a Yoga karaka for Capricorn and Aquarius ascendants. For Capricorn ascendant, Mars owns the 5th and 10th house and for Aquarius ascendant, it owns 4th and 9th house.

Exceptions to the rule above:

Jupiter, Mercury, Sun and Moon never become a Yoga karaka planet for any ascendant.

Jupiter and Mercury both own the Kendra houses which form the Kendradhipathi Dosha in Sagittarius, Pisces, Gemini and Virgo ascendants, and don't fulfill the condition of the Yoga Karaka planet. 

Sun and moon are luminaries and own only single sign don't fulfill the criteria for the Yoga Karaka planet.

In a nutshell, only 50% of the rising signs have the Yoga Karaka planet. Aries, Gemini, Virgo, Scorpio, Sagittarius and Pisces don't have any Yoga karaka planet.

Results:

Yoga karaka planet confers excellent results during its dasha (major planetary period) and antardasha (sub-period). Yogakaraka planet is a great indicator of good fortune, success, and positive results, particularly when the planets involved are strong and well-placed in the horoscope. A native can reach at extreme heights during its dasha and antardasha.

A Yoga karaka planet even if it is placed in 6th,8th and 12th houses (Dusthana houses) gives good results.
