Through Vedic astrology we can find which planets in your horoscope are going to benefit you and which planets are going to harm you. This can be found based on your ascendant sign. Your ascendant sign is very important sign in your birth chart. Based on your ascensant sign we come to know the sign of each house in your horoscope. Each ascendant has certain planets disposed towards it favourably, unfavourably and neutrally which I have described below. This details will be useful when predicting the results of Dasas. Based on the house each sign occupy, every horoscope has benefic lords, malefic lords and neutral lords. These of course have nothing to do with the natural classification of planets as benefics and malefics.
In any horoscope the benefics or benefic lords are
(1) First house lord, other than the Moon;
(2) the 5th and 9th lords (Thrikonadhipathis);
(3) lords of the 4th, 7th and 10th when they do not happen to be natural benefics.
The lord of the 9th is decidedly more benefic than the lord of the 5th. Similarly lord of the 10th is more benefic than that of the 7th while the lord of the 4th is the least benefic.
The malefics or malefic lords in a horoscope are
(1) Lords of the 3rd, 6th and 11th houses;
(2) lords of the 4th, 7th and 10th houses (Kendradhipathis) if they happen to be natural benefics.
Again among the malefics the 11th lord is the worst malefic, the 6th less malefic while the 3rd the least malefic.
The neutrals in a horoscope are
(1) The Moon—when he is lord of Lagna,
(2) the Sun or the Moon as the 8th lord,
(3) the Sun or the Moon as the lords of the 2nd and 12th.
Benefics and Malefics for each Lagna

Jupiter, the Sun and Mars are benefics. Jupiter is the best benefic. The next benefic is Mars. Saturn, Mercury and Venus are malefics. Mercury being the greatest malefic as lord of the 3rd and 6th.
The best benefic is Saturn as he owns the 9th and 10th. Mercury, Mars and the Sun are also benefics. Jupiter, Venus and the Moon are evil planets but Venus may be declared a neutral as he is lord of Lagna or ascendant.
Venus alone is the most beneficial planet for this Lagna. The most malefic is Mars as he is lord of the 6th and the 11th. Jupiter and the Sun are also evil. The Moon and Mercury may be classified as neutrals.
