Astrology, Vedic astrology, Indian astrology, Parashar Astrology, Bhrigu Astrology, Jaimini Astrology

Astrology is the science which comprises the study of heavenly bodies in relation to elements and creatures on the earth, particularly the human beings. Statistical data reveal that human beings are influenced by the movement of stars and planets. There are various methods to assess and arrive at conclusions about certain areas of life in Astrology.

The planetary aspects are modifying and determining influences in a birth horoscope. Unless aspects are properly computed and studied, the necessary modifications cannot be read and the delineations not being properly made in Astrology. The influence of a planet in a house can be understood only under the perspective of its sign placement and aspects it receives, for its own influence undergoes great modification by these two factors. In other words the natural sympathies and antipathies of the aspect and aspecting planets are the keys in delineating the aspects in Astrology.

In Vedic Astrology all aspects are counted from sign to sing. The benefic or malefic influence of an aspect greatly depends upon the relation of aspecting and aspected planet e.g. the aspect between the Sun and Saturm is bed one for both planets being natural enemies to each other. But in Dasa context i.e. in their mutural Dasa and Bhukti for a Tauras Lagna native this aspect is good one, for then the two planets work as functional benefics.

In Vedic Astrology all the planets have a quarter (1/4) glance or aspect on the 3th and 10th houses and planets there in, from their own placement; a half (1/2) glance therein: a there-quarter(3/4) glance on the 4th and 8th on houses and planets there in and a full glance or aspect on the 7th house and planets there
In other branches of Vedic Astrology viz Tajaka and Jaimini different aspects are used. In Jaimini all movable signs aspect all fixed signs except the adjacent ones. All fixed signs aspect all movable signs except the adjacent ones. All common or mutable signs aspect each other. This theory of vedic astrology applies also to the planets in such signs. In Tajaka system the scheme of aspects of western Astrology is followed including of influences of planets in aspect.

In exception to general quarter etc. glances Saturn, Mars and Jupiter have special aspects also. Saturn in addition to his 7th house full aspect also aspects the 3rd and 10th houses from himself with full aspect. This means that if Saturn is in Taurus, he aspects Cancer, Scorpio and Aquarius and planets there in respectively. Mars in addition to his full 7th house aspect also aspects the houses and planets 4th and 8th from himself. And Jupiter in addition to his 7th house aspect also aspects the houses and planets 5th and 9th house from himself. The special and 7th house aspects of Saturn and Mars are considered bed, for these two planets of Saturn and Mars are considered bed, for the two planets being natural malefics. The special and house aspects of Jupiter are considered good being the aspects of greatest fortune in vedic astrology

Generally the aspect of Jupiter over the Moon is considered good but for a Taurus Lagna native this aspect is not as good for a Cancer Lagna native. In the former case both are functionally evil while in the latter functionally and naturally very auspicious. Similarly, the aspect between the Moon and Mars is generally evil. For a Virgo lagna native this is disastrous while for a Cancer lagna very auspicious. The effects of such aspects are functional particularly in the Dasa and Bhukti of Planets concerned.quote:Vedic astrology.

The 3rd aspect of Saturn is referred to as sextile aspect in Western Astrology; the 4th and 10th aspects of Mars and Saturn as Squares; the 8th aspect of Mars as quincunx or in conjunct, the 5th and 9th aspects of Jupiter as trines and the 7th aspects of Western all the planets as opposition aspect. These aspects of Western Astrology are reciprocating aspects I.e. both the Planets mutually aspect each other.

In western Astrology matual longitudinal distances between the plants determine the type of aspect and its nature. The following are major Western aspects-

Conjunction	When the planets are on the same longitude.
Sextile	When the Planets are 60 degree apart.
Square	When the Planets are 90 degree apart.
Trine	When the Planets are 120 degree apart.
Quincunx	When the Planets are 150 degree apart.

When the two planets are at the same side declination either on the same side or in opposite sides of the celestial equator. Parallel is strictly a position actually not an aspect. The position is such that both planets be in north declination or both be in south or one north and other south of the celestial equator.

Certain orbs of influence are allowed. Orbs Means when the aspect begins or ceases to show its influence. The intensity of aspect is full when the planets are exactly at the above mentioned degrees apart. The orbs of aspects are areas of their influence around the planets in aspect and very with the intensity of aspect. The orbs of various aspects are:

Conjunction	9 degree
Square	8 degree
Trine	8 degree
Sextile	7 degree
Quincunx	2 degee
Opposition	9 degree
Parallel	1 degree

We may allow 3 degree more to the Sun and 2 degree more to the Moon for their luminosity. For aspects on the Ascendant, M.C., Descendant and 1.C 5 degree or 6degree orb is enough.
The influence of an aspect begins when the faster moving planet is behind the slower moving planet by degrees of orb mentioned for a particular aspect.

The influence of an aspect ceases when the faster moving planet is ahead the slower moving planet by degrees of orb mentioned for a particular aspect.
For example if the Moon 18 degree and Mars 27 degree are in Aries, the conjunction has just begun and if Mars 18 degree and the Moon 27 degree are in Aries, the conjunction is just to cease. For Quincunx aspect planets should be 150 degree or 210 degree apart. Taking 2 degree orb of influence, this aspect begins when the planets are 148 degree apart, full when exactly 150 degree apart and ceases when 152 degree apart.

All sings of the same quality are in square (90 degree) to each other. All signs of the same element are in trine (120 degree) to each other. Aspects are usually formed between the signs and the planets there in. Thus a planet in 2 degree in Aries is in square to a planet in 2 degree Cancer, the sign same quality and in trine to a planet in 2 degree Leo, the sign of same element A planet in 2 degree Aries is also in trine to a planet in 29 degree Cancer according to theory of orbs of influence. Such aspects are accepted by Western Astrologers and are supposed to be weak. Beginners should not confuse themselves with these and should stick only to aspects formed from sign to sign.

Some Western Astrologers even consider aspects from house to house irrespective of the longitudinal distances between the planets and occupied by them.
