Nakshatra Dasas (like Vimsottari) use the position of the Moon to calculate the Mahadasas, Antardasas at birth time. This is known as one of the most fruitful attempts in Vedic astrology.
K.P. astrology tries to generalize this attempt. Not only the Moon, but all planets are taken into account. So all planets (including house cusps) are treated like the Moon, and their corresponding lords and sublords are calculated. These lords play an important role in K.P. chart interpretation.
But the approach of K.P. lords can be extended to all Nakshatra Dasas. So we can get K.P. lords for Yogini and other Dasas, too.
Special attention should be spent to the lords of planets that are not included in the resp. Dasa. E.g. Ketu is not included in Yogini Dasa, so his lords may be interresting indicators for Moksha during Yogini periods.
