Kaal Sarp Yog Puja also leads to many misunderstandings as different astrologers and different natives interested in astrology preach and do this puja in different ways.
The most important step in performing any kind of puja to rectify any dosh in a horoscope is to perform the chant of a Mantra specified to reduce the strength of that dosh and this chant amounts to a number of 125,000 in most of the cases. For example, a Kaal Sarp Yog nivaran puja should ideally include a chant of 125,000 Kaal Sarp Yog nivaran mantras and rest of the procedure is built around this chant. To start with Kaal Sarp Yog nivaran puja, a specific day is chosen for the start and completion of this puja which is decided according to the horoscope of the native.
At the day of starting of this puja, a Sankalpam or resolution is taken by the Pandits which are usually 5 to 7 in number. In this Sankalpam, the head Pandit or the main Pandit takes an oath in front of Lord Shiva that he and his other assistant Pandits are going to perform a chant of 125,000 Kaal Sarp Yog nnivaran mantras for a specific person who is the native and whose name, his father's name and his family surname is also mentioned in Sankalpam. The names of the Pandits doing this chant are also mentioned, the days taken to complete this chant are also mentioned and the specific wishes required by the native as a result of this puja are also mentioned and this is the first step which starts a Kaal Sarp Yog nivaran puja.
