In Vedic astrology aspects holds very vital place. Aspects mean casting impact. Generally every planet aspect 7th house from its original position in Janam Kundli but Jupiter, Mars and Saturn cast additional aspects apart from 7th house. Mars cast aspect on 4, 7, 8th house from its natal position in Birth chart. Jupiter cast impact on 5, 7, 9th house from its original position in Vedic horoscope. Saturn cast aspect on 3, 7 and 10th house. Aspect as like Mooltrikona, Exaltation signs hold very strong place. If planet is benefic in chart so it will give benefic aspect to 7th house from its sign. For ex- Jupiter is in ascendant so it will affect 7th house beneficially. So what does it means? As 7th house stands for marriage, spouse, married life etc. It means that married life can ride smoothly, spouse and bride can have better communication in there married life, chances of better understanding can be there but for complete compatibility we had to look Ashtkoot Guna Matching, Manglik dosa and other things also. Here aspect give possibility in terms of marriage if person 7th house is malefic and malefic planets are present in 7th house as Jupiter is casting positive impact on 7th house, so with remedies of Jupiter 1st and indirectly 7th house can be strengthened and chances of marriage can be strengthened to some level.
But situation can go in reverse way also if malefic planet like Saturn is in deliberated sign so 7th, 3rd and 10th house can have negative aspect also. Like if Saturn is in 1st house so it will cast negative impact upon 3rd, 7th and 10th house. As 3rd house stands for brothers, communications, courage etc so when Saturn comes in 1st house or in 3rd house in transits then relationship with brothers can face some hardships, similarly for 7th house relationship with bride or spouse can had some differences, there can be delay in Marriage as Saturn signifies delay. For 10th house career opportunities can be limited, Jobs promotion can take beating, and even job layoff and worst thing will be if Sade Sati is going on that will add fuel to fire.
Now we comes to Mars if Mars is in 1st house, so according to Vedic astrology rules person is manglik straight away this is an enough reason for fear as in our society Manglik is dreaded term which is hindrance for marriage. So coming to the point Mars will cast impact on 4th, 7th and 8th house in birth chart. Now if Mars is malefic in 1st house then results will be negative. One such result is described above, other effects would be it will affect courage, vitality of person as Mars is in 1st house; person had to take special care of his immunity. Person had to be very careful while He/She is driving. For 4th house there can be loss of wealth, wealth generation possibilities can be limited. Special care had to be taken for Money. Similarly for 8th house there can be dejection, delays in work, sorrows and griefs, rejection and person can feel lonely, depressed when Mars comes in 8th or 1st house.
So we had seen Aspects can be benefic or malefic it all depends upon placement of planets In particular sign. So aspects give strength to house or aspects can make the house weak if planets are casting negative impact. But there is one significant point to note that besides aspects, we should look placement and conjunction of planets in particular house. Astrologer had to study overall chart then only conclusion can be made. Aspects are only one part and with remedies negative aspects can be pacified to some extent.
