As we know that, in the preparation of a horoscope, planetary positions will remain fixed in their respective longitudes. The planetary positions continues to be fixed but practically there is no stoppage to the planetary movements. All planets have different time period to move from one sign to another. This movement gives rise to the stimulation of radioactive disintegration which produces psycho physical changes in character of an individual and disposition.
While calculating the Dasha and Bhuktis of a chart, due importance should be given to the Gochar movement of the planets. This further clarifies the effect of Dasha, Antardashas and Bhuktis in that period. Since, Moon is the fastest moving planets, hence for Gochar results Chandra Kundli [position of planets with reference to the Moon] is considered to be more prominent.
The Sun is considered to be beneficial when it transits in 3rd, 6th, 10th and 11th house from the Moon sign. Although, the Sun is beneficial in 3rd, 6th, 10th and 11th house from Moon sign but if any planet (except Saturn) is placed in the 7th house from the transit Sun, the benefic effects of the Sun are lost to a great extent. For example, if Moon sign is Scorpio then transit of the Sun in Capricorn is beneficial but if any planet is transiting in Cancer then the benefic results will be diminished. The effect is same for 6th house, 10th house and 11th house also.
The Moon is considered to be beneficial when it transits on 1st, 3rd, 6th, 7th, 10th and 11th from its original position in the horoscope. But, the benefic results are diminished when any planet except mercury transits in 5th, 9th, 12th, 2nd, 4th and 8th house from transit moon respectively.
Mars is benefic in 3rd, 6th and 11th house from Moon in horoscope but the beneficial results are lost if any planet transits in 12th, 9th and 5th house from Transit Mars.
Mercury is considered to be beneficial when it travels through 2nd, 4th, 6th, 8th, 10th and 11th house from Moon sign in horoscope. But, it should be noted that if any planet transits in the 5th, 3rd, 9th, 1st, 8th and 12th house respectively from transiting Mercury.
Jupiter is considered beneficial when it transits 2nd, 5th, 7th and 9th house from the Moon sign provided no planet transits 12th, 4th, 3rd, 10th and 8th house from the transit Jupiter.
Venus will be beneficial if it transits in the 1st, 2nd, 3rd, 4th, 5th, 8th, 9th, 11th and 12th house from Moon in the horoscope. But, there should be no planet transiting in 8th, 7th, 1st, 10th , 9th, 5th, 11th, 3rd and 6th house from the transiting Venus.
Saturn is benefic in 3rd, 6th and 11th house from the Moon sign in the horoscope. But, the transit of any other planet transiting in 12th, 9th and 5th respectively from the transiting Saturn reduces the good results of Saturn.
Taking these factors into consideration and analyzing the Dashas and Bhuktis of horoscope we can find out more accurate results of the current period. For example, if by birth the Sun is favourable and if the Dasha of Sun is going on, then ignoring the Gochar movement we will predict good results but if the Sun is in the Moon Rashi or 2nd from Moon Rashi or is in 4th, 5th, 7th, 8th, 9th or 12th house from Moon Rashi then the results may not be good as expected. Hence, Gocharphala is very important in the terms of relativity and accuracy of analysis.
