This is the key lesson among all the lessons. If you are thorough in this, it will be easy for you to predict.
There are totally 12 zodiac signs. So there would be totally 12 lagnas. For each lagna, there would be functional benefic planets and functional malefic planets depending on the houses planets own. These are known as functional benefic planets and functional malefic planets. You should not get confused them with natural benefic planets and natural malefic planets. Planets give different results as natural benefic planets and functional benefic planets. Same is the case with natural malefic planets and functional malefic planets. Any planet, be it a natural benefic or natural malefic, becomes a functional benefic when it owns a benefic house. Similarly, any planet, be it a natural benefic or natural malefic, becomes a functional malefic planet when it owns malefic house. You already know what the benefic houses and malefic houses are. We discuss each lagna one by one.
Aries as the lagna / first house
Mars becomes the first and 8th houses lord, first being good and 8th being bad. Mars gives both the results as first lord and 8th lord too during its sub and sub-sub periods. (Good and bad). But the native would have more good and less bad as Mars owns both the houses.
Venus becomes the lord of 2nd and 7th houses and gives good results as lord of these two good houses. But Venus also becomes a Maraka planet as lord of two Maraka houses, 2 and 7. Please remember that you have to take the Maraka effect as a side effect.
There is one more principle which I did not explain earlier as there is a possibility of the students getting confused. That is known as Kendra Adhipatya Dosha. This means that if a natural benefic planet (Jupiter, Venus or Mercury) owns a Kendra house, it turns into a functional malefic planet. Similarly, if a natural malefic planet (Mars, Saturn and Sun) owns Kendra, it turns out to be a functional benefic.
If you apply this principle to Venus here, it becomes Kendra lord and being a natural benefic, turns into a functional malefic. This means the Maraka side effect of Venus would be more to the people of this lagna.
So, you must understand that Venus gives both good and bad results for this lagna.
Mercury is lord of 3rd and 6th houses. 6th house is bad. 3rd house is good but it is bad too as it is 8th to 8th. So Mercury is both good and bad but certainly less good.
Jupiter is lord of 9th and 12th houses and gives the results equally. As 9th lord it is good but as 12th lord it is bad.
Saturn is lord of 10th and 11th houses. Both houses are good But, as 11th lord it is badhaka also (kindly refer to your lesson on principles to remind yourself of badhaka). As tenth lord, it turns into good due to Kendra Adhipatya Dosha Principle and does good. So, Saturn for this lagna is both good and badhaka too.
Moon as 4th lord is good and Sun as 5th lord is also good. If they are situated together in any good house, they produce very good results during their combined periods. Same results would follow if they are in mutual aspect from good houses. Again, same results would follow if Moon and Jupiter are also together or in mutual aspect.
Sun and moon generally do not give bad results unless they are very weak in the horoscope. Generally, any planet owing a bad house is bad. For example, lord of 6th house is functional malefic. This means that planet owning the 6th house gives bad results during its period. This is a predictive principle for all planets. But Sun and Moon are exempted from this principle. You have to understand that if Sun or Moon is lord of 6th or 8th or 12th house, it does not give bad results. This is what astrology says.
My point is that when Sun and Moon do not suffer from lord ship of bad houses, the principle of Kendradipatya Dosha too does not apply to them. Actually, if you apply this principle to Moon as 4th lord, it turns into a functional malefic. But this principle is operative for Moon / Sun only if they are weak in the horoscope. Otherwise, Sun or Moon gives good results as lord of Kendra too, if they are friendly to the lagna lord. This should never be forgotten. The other way to interpret is that if Moon or sun is weak as 4th, 7th, 10th lord, then only it gives bad results due to kendradhipatya dosha. These things should always be kept in mind while reading a horoscope.
Taurus as the lagna
Venus becomes the first and 6th houses lord, first being good and 6th being bad. Venus gives both the results as first lord and 6th lord too during its sub and sub-sub periods. (Good and bad). But the native would have more good and less bad as Venus owns both the houses.
Mercury is lord of 2nd and 5th houses turning itself into a planet of value. This means that during the sub / sub –sub periods of Mercury, the native would get recognition and his / her services would be on demand. On the whole Mercury gives very good results if it is strong in the horoscope. Mercury becomes maraka too but the maraka effect would be nil as it is a planet of value. But if it is weak, the maraka effect would dominate.
Moon is good as third lord and Sun is also good as 4th lord. Due to Kendradi Patya Dosha, Sun becomes good. But Sun would not give the full fledged good results as 4th lord as it considers Venus as enemy. On the other hand, if it is weak, it spoils the domestic happiness of the native as lord of 4th house.
Mars is 7th and 12th lord. As 7th lord it turns good due to Kendradipatya dosha. But as 7th lord it is Maraka too. Again it is bad as 12th lord. So it gives good and bad results to the native during its periods, sub or sub-sub. Mostly bad results would follow.
Jupiter is lord of 8th and 11th houses and gives mixed results as lord of these two houses.
Saturn is yoga karaka planet for this lagna and gives good results if it is strong. But as 9th lord it is badhaka too and some trouble also would be there for these people from Saturn.
Gemini as lagna
Mercury is lord of 1st and 4th houses and turns good. Moon as 2nd lord is good, sun as third lord is also good. The maraka effect of Moon would be nil if it is strong. If it is weak, it spoils the native in finance and family matters represented by the house.
Venus as 5th and 12th lord gives mixed results. Mars is 6th and 11th lord becomes danger planet. The reason is that as 6th lord it is bad. 11th is 6th to 6th and because of this effect, as 11th lord also it is bad. Besides, Mars considers Mercury as enemy planet. So Mars is very dangerous planet for this lagna.
Jupiter as 7th and 10th lord turns into functional malefic due to kendradhipatya dosha. Again it is badhaka and maraka too. So if it is weak, it spoils the family relations and professional aspects of the native as 7th and 10th lord. Saturn is 8th and 9th lord and gives mixed results.
Cancer as lagna
Moon as lagna lord is good. Sun is also good as 2nd lord. The maraka effect of sun would be less as it considers Moon as its friend. Mercury as 3rd and 12th lord is bad. Venus as 4th and 11th lord turns in to bad due to kendradipatya dosha and badhaka. The reason is 11th house is badhaka for this lagna and as 4th lord, it turns bad due to kendradipatya dosha. Moreover, Venus considers Moon as enemy. Mars becomes yoga karaka planet as lord of Kendra and kona and gives very good results during its periods. Jupiter as lord of 6th and 9th lord is good and bad but less bad certainly if Jupiter is strong. Saturn is lord of 7th and 8th lord and gives mixed results. Saturn is maraka too for this lagna.
Leo as lagna
Sun is good as lagna lord. Mercury is planet of value as it is lord of 2nd and 11th houses. Its Maraka effect would be less. Venus is lord of 3rd and 10th house and is bad due to kendradipatya Dosha and due to lordship of 3rd house. Mars is yoga karaka planet and gives good results. But it is Badhaka too. Jupiter is both good and bad as it is lord of 5th and 8th houses. Saturn is also good and bad and also maraka. So its effect would be more as bad planet as it considers sun as enemy. Moon as 12th lord gives wastage of money and efforts.
Libra as lagna
Venus is lagna lord and 8th lord. So it is both good and bad but surely less bad. Mars is good as 2nd and 7th lord but maraka too. So it gives mixed results. Jupiter is bad as 3rd and 6th lord and gives bad results during its periods. Saturn is yoga karaka as lord of 4th and 5th houses and good. Mercury is good and bad as lord of 9th and 12th houses. Moon is good as 10th lord . Sun is also good but badhaka too and gives some trouble though it gives the results of 11th house. But surely less good will happen as it considers Venus as enemy.
Scorpio as lagna
Mars is both good and bad as first and 6th lord. Jupiter is planet of value as 2nd and 5th lord. Jupiter’s maraka effect would be less. Saturn is mixed as lord of 3rd and 4th houses. Venus is also mixed as 7th and 12th houses lord. The maraka effect of Venus would be more. Mercury is both good and bad as 8th and 11th lord. Moon is good as 9th lord but badhaka too. Sun is also good as 10th lord. Since it considers Mars as friend, kendradi patya dosha would not be there. The combination or mutual aspect of Sun and Jupiter, or sun and moon produces yoga karaka effect.
Jupiter is very good as first and 4th lord. Saturn is mixed as lord of 2nd and 3rd houses. Mars is mixed as 5th and 12th lord. Venus is bad as lord of 6th and 11th houses. Mercury is maraka, badhaka and turns bad due to kendradipatya dosha. Moon gives troubles as 8th lord if it is weak. Sun is good as 9th lord. The combination of Sun and Jupiter or Jupiter and Mars in good houses or their mutual aspect gives good results of yoga karaka.
Capricorn as the lagna
Saturn is good as first and second lord. Jupiter is bad as lord of 3rd and 12th houses. Mars is good as 4th and 11th lord but it is badhaka too. Venus is yoga karaka planet and gives very good results. Mercury as lord of 6th and 9th gives mixed results. Moon as 7th lord is good but maraka too. If it is weak, the maraka effect would be experienced. Sun is bad if it is weak as 8th lord.
Aquarius as lagna
Saturn is both good and bad as first and 12th lord. Jupiter is planet of value as 2nd and 11th lord and is very good. Mars is mixed as lord of 3rd and 10th houses. Venus is yoga Karaka and very good.

Pisces as lagna
Jupiter is very good as lord of first and tenth houses. Mars is planet of value as second and ninth lord and gives very good results. Venus is bad as lord of 3rd and 8th houses. Mercury is maraka, badhaka and also bad due to Kendradipatya dosha as it is lord two kendras, 4th and 7th houses. Moon is very good as fifth lord. Sun is bad as 6th lord if it is weak. Saturn is both good and bad as lord of 11th and12th houses. Please note that if a planet is yoga karaka or planet of value or lord of good house such as fifth or ninth house, or 2nd / 11th house, it gives good results during its sub / sub –sub periods if it is strong only in the horoscope. If it is weak, the results would be unfavorable. This should not be forgotten.
