According to prevalent definition of Veshi Yoga in Vedic astrology; if in a horoscope, there is one or more than one planet in the house next to the house of placement of Sun, Veshi Yoga is formed in the horoscope. Veshi Yoga may bless the native with good results related to character, reputation, fame and many other things.
The placement of Moon, Rahu and/or Ketu only, in the house next to the house of placement of Sun is not considered for the formation of this Yoga. Hence one or more than one planet other than Moon, Rahu and Ketu should be placed in the house next to the house of placement of Sun in a horoscope, for the formation of this Yoga in that horoscope.
In real practice, Veshi Yoga is not seen producing such results when only the aforementioned conditions are met. Hence more conditions should be met in order for this yoga to be formed effectively in a horoscope. If Sun is functionally benefic in one such horoscope, this yoga may produce better results. If the planet/planets placed in the next house are also benefic; Veshi Yoga may produce even better results.
Taking an example, suppose Sun is placed in the first house of a horoscope in Virgo and exalted Saturn is placed in the second house in Libra. Sun is malefic in this horoscope. Saturn is partly benefic and partly malefic in horoscopes with Virgo ascendant. In this case, Veshi Yoga may not be formed in the horoscope or it may not do much good to the native; though the primary conditions are met. The concept of a planet being partly benefic and partly malefic has been explained in the book ‘Pitra Dosh – Ancestors are Calling (Revised Edition)’.
Taking another example, suppose Sun is placed in the first house of a horoscope in Leo and exalted Mercury is placed in the second house in Virgo. In this case, Veshi Yoga may be formed in the horoscope, since both Sun and Mercury are benefic. Hence the native with may witness good results related to character, reputation, profession, finances, health and a number of other things.
Once the formation of Veshi Yoga is confirmed in a horoscope, the next factor to check is its strength. The strength of this yoga is calculated through the placements of planets involved in its formation in various signs, nakshatras and navamshas; as well as through the influences of other benefic and malefic planets on them. The overall theme of horoscope and running times (Mahadashas) also affect the strength of this Yoga.
Taking an example, suppose Sun is placed in the first house of a horoscope in Leo, in Aries navamsha of Magha nakshatra and exalted Mercury is placed in the second house in Virgo, in Virgo navamsha of Chitra nakshatra. Sun and Mercury are strong in their respective signs as well as navamshas. Hence strong Veshi Yoga may be formed.
Looking at the running times; when Mahadashas (planetary periods) of malefic planets are in effect; benefic effects of Veshi Yoga may reduce. When Mahadashas of benefic planets other than the ones involved in the formation of this yoga are in effect; benefic effects of this yoga may increase. When Mahadashas of the planets involved in the formation of Veshi Yoga are in effect; the native may witness maximum benefits through this yoga. For instance; in the recent example, the native may benefit the most during Sun Mahadasha and Mercury Mahadasha.
