Durudhara

Durudhara Yoga is formed when planets other than the Sun occupy both the second and the twelfth places from the Moon, so that the Moon is flanked on either side. It is the fullest of the three lunar flanking yogas and is read for wealth, comfort, generosity, a good vehicle and a well-supported life, the imagery being of the mind attended and provided for on both sides. Because the Sun is excluded from the count and Mercury and Venus are never far from the Sun, the yoga depends chiefly on the outer and slower bodies. Its opposite, kemadruma, arises when neither place is occupied. Taken together the four form a small, coherent and genuinely classical subsystem, and they are a good example of the kind of structural reasoning, based on position relative to a significator rather than on sign or aspect, that distinguishes Jyotisha from western technique.

Kemadruma, the absence case this trio is defined against, is given a fuller classical condition than simple emptiness on both sides of the Moon: Brihat Parashara Hora Shastra and later texts typically also require that no planet other than the Sun be conjunct the Moon itself and that the Moon not stand in a kendra from the Ascendant, before the unfavourable Kemadruma reading, poverty, instability, a struggling and friendless disposition, is allowed to apply in full. Because these additional conditions are easy to overlook, popular accounts often call any chart with an empty second and twelfth from the Moon Kemadruma outright, while stricter classical reckoning treats many such charts as escaping the yoga entirely once the kendra and conjunction exceptions are checked, a discrepancy between traditional and casual modern readings of the same nativity.

Durudhara completes the lunar group: planets on both sides of the Moon, in the second and the twelfth from it, so that the Moon is attended in both directions. It is read as the strongest of the four and is credited with resources, comfort and support from others.

Seen together the four make an unusually clean structure. One variable, whether each neighbouring sign is occupied, generates four cases, and every chart falls into exactly one. Both sides occupied is Durudhara, the second only is Sunapha, the twelfth only is Anapha, neither is Kemadruma. Nothing else is possible.

That tidiness is the set's strength and its limitation. It is easy to apply and impossible to dispute, since no judgement is involved in determining which case a chart shows. But it is also a partition of a single variable, and it distributes all charts among four buckets whose meanings were assigned by the logic of the partition rather than derived from anything outside it. Three of the four are favourable and one is not, which is roughly the distribution the geometry produces.

The atlas records the set as the tradition states it, notes the structure, and takes no position on whether the lunar combinations describe anything. Nothing here is a prediction about any person.
