CONSTELLATIONS OR NAKSHATRAS
The Zodiac or Rashi comprises of 360 degrees. There are 27 Nakshatras or constellations in it. The value of each constellation or Nakshatras is 13 degrees and 20 minutes. Each Nakshatra is divided in padas or charan, every Nakshatra has 4 padas or charan. These 27 Nakshatras (constellations) complete the entire circle of 360 degrees of the zodiac.
Janma Nakshatra is the Nakshatra in which the Natal Moon is placed at the time of birth.We consider Janma Nakshatra for calculating the dasha period.
As per our Hindu Mythology, Moon had married all the 27 daughters of King(Prajapati) Daksha, who are the 27 nakshatras in the sky. But, Moon loved to spend time with only one his beloved queen Rohini Nakshatra, which is also the exaltation point for Moon. Other wives (Nakshatras) complained to their father (King Daksha), repeated request to Moon by King was unable to change Moon's nature, finally King Daksha got angry and cursed Moon, causing it to wane in size. Moon started diminishing in size. Since the consequences of this was not good, all Devas requested King(prajapati) Daksha to withdraw the curse. King was given assurance that Moon will visit all his wives, since the curse cannot be revoked completely, King Daksha said Moon will regained his strength for half a month, that is the reason Moon transits all 27 nakshatras in a month, completing the zodiac orbit causing Amavasya and Poornima by waxing and waning in size.
