The following points need to be evaluated for a good astrologer:
- Mercury, Jupiter give the capacity to learn & advise. Mercury gives mathematical ability also.
- Saturn, Rahu, Ketu, Venus give the inclination to venture into metaphysics.
- Uranus is considered very important in KP & western astrology for a good astrologer as it has connection to space research (Uranus represents Aquarius in western astrology).
- Moon is important as Moon represents mind and astrology is a lot about psychology. Also, Moon can give psychic ability to an astrologer helping him/her in predictions.
- 2nd house gives the potential to study, research, accumulate knowledge and for spoken words.
- 3rd house of consultation/upadesha.
- 8th house gives the inclination to delve into hidden, mysterious and transformative things.
- If 5th and 9th houses are prominent, the astrologer can have spiritual understanding also giving him/her wide perspective.
- Presence of fire element, as fire element gives problem solving ability. This can be checked via fiery ascendant and/or fiery grahas etc. Mars gives rational mind that likes to attack problems due to fiery nature and hence is particularly useful.
- Prominent 10th & 11th houses point towards success but this is true in general and is not specific to astrology.
