Kartari Yoga in Vedic Astrology
This is also called as scissors yoga. This yoga is produced when two benefic or malefic planets surround the lagna or the Moon or any other house. When two planets are surrounding a particular house, if any planet sitting in that house will also get affected. Imagine two pious people sitting next to a sinful person. Because of their positive aura, the environment surrounding them will become pure. In that environment, the sinful person also loses his sinful mind set. Imagine another scenario, two bad people are neighbours to a pious person. Because of their behaviour and living style, the pious person finds uncomfortable to live peacefully. Even though he may not do any harm to anybody, he will lose out his peace of mind. In this situation he may not help others much. Same things happen in the planetary world also.
There are two types of Kartari Yogas are possible: Shubha-kartari Yoga (Benefic yoga) and Paapa-kartari Yoga (malefic yoga)
Shubha Kartari Yoga
When natural benefic planets occupy 2nd house and 12th house from a particular house, that house is said to be in a Shubha-kartari Yoga. It is more important if that house happens to be the lagna. The natural benefic planets are Jupiter, Venus, Mercury and waxing Moon. When these planets surround any particular house or planet, the positive significations of that house will get enhanced. Even if malefic planets are posited in that house, the malefic characters of that planet is reduced.
It is a malefic yoga. When natural malefic planets occupy 2nd and 12th house from a particular house, that house is said to be in a Paapa-kartari Yoga. Again, it is more malefic if the malefic planets are associated with the lagna. The natural malefic planets are Saturn, Mars, Rahu and Ketu. Many will consider Sun as malefic. But if it only conjunct very near in degrees, then it will combust other planets. Otherwise it may not harm much.When two malefic planets surround any house or planet, the positive significations of the house will be affected. The planet sitting in that house also will lose its strength.
The paapa kartari yoga on malefic planets (malefic planet is surrounded by other malefic planets) is much more harmful. Because negative energy is influenced by more negativity.
The results of the kartari yoga are not unique. It depends on in which house the kartari yoga is forming. The yoga affects the significations of the particular house. And also the result will depend on the planets associated. For example, if paapa kartari yoga is happening in 4th house, the native will find it difficult in the matters related to 4th house. The native will go through lot of tensions leading to loss of happiness, will find difficulty in basic education, will face problems household matters, dealing with land, vehicles etc. So it may not deny the results completely, but will find it difficult in achieving it. Sometimes the native may have to sacrifice something to achieve other goals. In the same manner, shubha-kartari yoga will produce benefic results to the native. He will be able to achieve the goals related the house significations very easily. When shubha-kartari yoga is forming in lagna, the native will be very fortunate, life will move very smoothly.
The concepts can be used in mundane astrology as well. When kartari yogas are forming in transits, there will be changes happening in the matters related to the house. Countries related to the house will be affected by this yoga. We can predict natural calamities based on the planets associated when paap-kartari yoga is formed.
