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 betweenRahu (Moon's North Node) and Ketu (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.
