In Hindu astrology, Varshaphala (annual horoscopes) or the Progressed Horoscopes are made using Kesava and Neelakantha’s Tajika System. This lets the astrologer predict important events that will happen soon. The Lagna, or rising sign, of a yearly horoscope, is based on the moment when the Sun, after going through all twelve zodiac signs, returns to the same place it was when the person was born. Muntha is a made-up mathematical point that plays a big part in this way of making predictions.
Annual horoscope or Varshaphala is usually studied using the Tajik methods by North Indian astrologers. In the Tajik method aspects of planets are different as compared to the usual Parashari aspects. As per my Guruji Shri K.N. Rao, the annual horoscope or Varsha Kundali can be studied using ‘Parashari’ aspects of planets to give general indications about the trends for the upcoming year of a native. Shri K.N. Rao has demonstrated this technique in many of his books more prominently in ‘Astrology, History, Mystery, and Horoscopes’.
As per this system, we have to locate a house in the annual horoscope which get the aspects or association of more planets. The house and its lord associated with more planets is marked first as that area would indicate the general trends for the year concerned. For example, if in an annual horoscope majority of planets are influencing the 5th house and its lord by their aspects or association then if the Varshaphala is for a child then his education will show an important rise or fall as per his birth chart, and if it is the annual horoscope of an adult recently married then ‘child birth’ event can be predicted depending upon other factors.
Similarly, if the 7th house/lord is becoming prominent in the annual horoscope then pay attention to the marriage part or business depending upon the native’s age and concerns. Also, Muntha(The advanced ascendant is the Muntha. It moves one Rasi or Sign per year, starting from the birth ascendant. It is found by adding the number of the ascendant at the time of birth to the number of years that have passed between birth and the year for which the Progressed Annual Horoscope is made, dividing that number by 12, and then casting away the result. It has to do with your birth chart. In a continuous loop, it would end up in the same sign as the rising sign after 12 years.)
or Progressed Lagna and its lord are also marked in the annual horoscope as they are also very important points to study. It is also checked which house of Janma Lagna is becoming Muntha in the annual horoscope.
As per Tajik Neelkhanti, the Muntha in the 2nd, 4th, 6th, 7th, 8th, and 12th house in the annual horoscope is considered inauspicious. In houses other than this Muntha is considered good.
Here I have mentioned some examples
Case 1. Birth Chart (Female)

Venus is related with the 2nd house of the Kundali, and Saturn is the 7th Lord and Lagna Lord in the Navamsa chart. She gets married in the year 1999 during the Shukra Shani Dasha.
Case 1. Varsha Kundali (Annual horoscope)

As we can see in the yearly horoscope for 1999, a greater number of planets were related with the second and fifth house; the second house, which we also take for marriage, and the fifth house, which was prominent in that year’s Varsha Kundli. As a result, she was blessed with a child within the first year of her marriage.
Second example – career break
Case 2. Birth chart (Male)

In 2017, the native was transiting Rahu-Jupiter Dasha. The Dasha of 6-8 is not auspicious, and the Rahu-Shani conjunction in the lagna sometimes brings defamation, and Jupiter has moved to the 8th house in the Dashmansh chart. Which indicates a career break
Case 2. Annual horoscope (Muntha in Aries)

If we look at the 2017 Varsha Kundali, Muntha was passing over the 10th lord moon in the 7th house, which is a sign of a significant career event. Most of the other planets were in the 6th through 12th houses, which is not favorable for the native.
Muntha, whose degree is the same as the birth ascendant, gives very good results when it is in the ninth, tenth, or eleventh house from the annual ascendant. It gives good results when it is in the first, second, third, or fifth house, but only bad results when it is in the fourth, sixth, seventh, eighth, or twelfth house. When unpleasant planets, especially Ketu, touch or join Muntha, bad things happen. When the Muntha-lord, or the lord of the sign that Muntha is in, is in the 4th, 6th, 7th, 8th, or 12th house, bad things happen.
