Ashtamangala prasnam is the ultimate diagnosis methodology in astrology due to its complexity in calculations and interpretations. It is not performed by the astrologer alone but is done by one of the family members or a girl child around 10 years of age. Two or more astrology experts together will decide on the calculations and interpretations. Ashtamangala prasnam uses omens and numerologies in it. And it is a method in which eight auspicious objects; ghee lamps, mirror, gold, milk, fruits, yogurt, book and white cloth are used.
