Kalasarpa yoga is considered to be one of the not so good Nabhasa Yogas. This is sometimes associated with physical deformity or moral weakness, misfortunes, deceit and treason. The positive qualities of this Yoga are that, the native can acquire a capacity to do arduous work, with exceptional success in the fields of studies, administrations, philosophy etc. Moreover one can fulfill his desires of his life, either in the materialistic concept or in the spiritual scope.
“Kala” means time,'Sarpa' means Serpent and “Yoga” means combination. So Kala Sarpa Yoga means that the soul is caught by the Serpent of time within the axis of Karma. It reflects unusual and unexpected life-situations experienced by a person, according to his Karma of the previous birth.
It is formed when all 7 planets considered in Vedic Astrology (Sun, Moon, Mars, Venus, Jupiter, Saturn, Mercury) are placed between Rahu (Moon's North Node) andKetu (Moon's South Node) in the natal chart. It is defined by the following sloka.
"Agre rahur atho kethu, Sarve Madhya gata graham| Yogam
Kalasarpakhyam,Nripa Sasya Vinasanam"
According to the above sloka “ Rahu must be ahead of the Ascendant and Ketu behind it; all the planets should occupy between them; no planet should be in conjunction with Rahu or Ketu . This is a definition for Kalasarpa Yoga.
"Sarvanabho gasthishta thiyagu Sikhino, Anthrala
rasigatha| 'Malyavadanthara rahithah Yatha thatha Kalasarpa Yogasyala"
"Anuloma vilomathkala Dwidhoyam Kalasarpayogascha| Anthoykthasch anistom karithi Poorvo maha subada"
"Sampoorna sakala vibhavaha Samastha Nripavandhithakhri Kamalayuga| Rajadhi Raja Rajo Virajathee Kalasarpa Yoga bhava"
From the above sloka, we can understand that: All the planets must be placed a between Rahu and Ketu continuously, forming a chain without any break. Only this formation can be taken as the Kalasarpa yoga.
The Ascendant can either be within the chain or outside the chain Either Rahu or Ketu can occupy the lagna. So the lagna has nothing to do with the formation of the Kalasarpa yoga. The yoga is of two kinds; one is called the “Anuloma” and the other the “Viloma” The “Anuloma” type produces excellent results, whereas the “Viloma” type produces undesirable results. In Anuloma type, Rahu is ahead within the six rasis from the lagna and Ketu occupies a position behind all the planets. Here, one will acquire higher position with all beneficent results. In Viloma type, Ketu is ahead within the six rasis from the lagna and Rahu is posited behind all the planets. Here, one will suffer the maximum and lose his benefits.
When all the planets are located or locked up between Rahu and Ketu, the planets can arrange themselves in various possible positions to activate the Kalasarpa yoga. Such conditions can be briefly mentioned as follows:
If the Sun is in the 8th house from Rahu, or When Rahu or Ketu is in the 8th house from Moon, Kalasarpa Yoga is activated. The Kalasarpa Yoga is predominant, when Rahu or Ketu is located in the 6th, 7th, and 8th house from the ascendant. When Rahu or Ketu is in Kendras, the adverse effect of the Kalasarpa yoga is greater. When Rahu or Ketu is in Trikona, the good effects of the Kalasarpa yoga predominant. Depending upon the movement of the planets either towards Rahu or Ketu, the yoga is named either as Kalasarpa yoga or Kalamrita Yoga.
Both the Yogas are formed, when all the planets are suitably located between Rahu and Ketu . Some astrologers consider Kalasarpa Yoga is Viloma type of Yoga and Kalamritha Yoga as Anuloma type of Yoga. In Southern states of India, yet one more condition is given. When Rahu goes towards its exaltation position, and the other planets follow suit, it is said to be a benefic yoga, giving good results to the native; on the other hand if Rahu goes towards its debilitated position followed by other planets, it is said to be a malefic yoga, giving bad results to the native.
One school of thought says that when lagna, Sun, Moon or any one of the planets is away from the sequence of Kalasarpa arrangement, the yoga is said to be nullified, but another school of thought insists that there will be nullification, only when two or more above said factors are away from such arrangement. So conceptually, it has been accepted that occupation of the planet between Rahu and Ketu is the essential condition for the Kalasarpa Yoga.
Since the Nodes of the Moon are associated with Karmic attributes, the yoga inflicts certain restrictions over a natal chart. It expresses karmic nemesis.
The Kalasarpa Yoga will be mostly operative between the ages of 39 and 45 years.
When the Lagna is not included in the yoga and goes out of the axis of Rahu and Ketu, lesser will be the adverse effect.
Kalasarpa yoga is not like other yogas generally formed by the combinations of Mars, Sun or Moon, producing enrichment or penury. The encirclement of all the planets in the natal chart by the two nodes makes the individual to enjoy the fruits of previous Karma. If a person suffers at the present birth due to the bad deeds of the previous birth (Sanchita Karma) and do good at this birth (good Prarabdha Karma), with Kalasarpa yoga being present in the horoscope, then the suffering in the present birth will be gradually changed into good. The native will have good worldly life with spouse and children.
It has been found that if Rahu or Ketu conjoins with any planet either in the ascendant or in the 7th house from the lagna, a partial cancellation of the yoga occurs, which results in Raja Yoga at the respective attributed house. The native will enjoy either good or bad according to the dispositions of the lords of the ascendant and the 7th house in the natal horoscope.
The impact of the Kalasarpa Yoga is greatly minimized, if three or more planets are exalted or in parivartana or the lords of the 2nd, 4th, 9th and 10th occupy the Trikona or Kendra houses, without debilitation, inimical positions or aspected by malefics.
Kalasarpa yoga formed during the transits of Rahu and Ketu plays a vital role in the mundane affairs, generally causing unexpected calamities. According to Vedic astrology, the yoga does not include the influence of the outer planets like Uranus, Neptune and Pluto.
