Vishakha
Vishakha is the 16th of the 27 nakshatras of Indian astrology. Degrees: 20°00′ Libra to 3°20′ Scorpio. Ruling planet: Jupiter; deities: Indra and Agni; symbol: a triumphal arch.
Personality
Determination. Vishakha gives the ability to reach a goal at any cost and to hold an intention for a long time. Its people are ambitious and energetic.
Weak spot: obsession with the goal and a tendency to sacrifice relationships and health for the sake of results.
Ruling Planet and Deity
The ruling planet, Jupiter, determines through which period of life the nakshatra's theme unfolds: in the dasha system, it is the ruler of the Moon's nakshatra at birth that determines which period a person's life begins with.
The nakshatra’s deities are Indra and Agni. In the tradition, they convey the nakshatra’s meaning more deeply than any description of character: they are invoked in rituals connected with this part of the sky.
Each nakshatra is divided into four "padas" of 3°20′, and in Jyotish the pada refines the description. Determining the pada precisely requires the time and place of birth.
Suitable Occupations
Tradition links the Vishakha nakshatra with the following fields: science, politics, sports, entrepreneurship, anything that takes persistence.
This is not career advice but a description of traditional correspondences. Your nakshatra is determined by the Moon's position, so you need your date, time, and place of birth.
Compatibility
In Kundali Milan, the Indian comparison of charts before marriage, the Moon's nakshatra determines most of the 36 compatibility points: Tara, Yoni, Gana and Nadi are calculated from it, while Varna, Vashya, Graha Maitri and Bhakoot come from the Moon sign.
Separately, the tradition takes "Nadi Dosha" into account: if both partners' nakshatras share the same nadi, the marriage is considered unfavorable. This is one of the most controversial parts of the system, and it is the reason perfectly good matches fall apart in India.
