Rashi System
The Zodiac Circle:
- The zodiac circle is a complete 360-degree circle.
Division of Zodiac Circle:
- This circle is divided into 12 equal parts, known as Rashi (zodiac signs).
- Each Rashi, therefore, covers 30 degrees of the circle.
Sub-Division of Each Rashi:
- Each Rashi is further divided into 9 equal parts.
- These parts are called Nava-amsha (ninth parts).
Calculation:
- One Rashi = 30 degrees.
- One Nava-amsha = 1/9th of a Rashi.
- Therefore, one Nava-amsha = 30 degrees / 9 = 3 degrees 20 minutes.
Total Divisions in the Zodiac Circle:
- Since there are 12 Rashi and each Rashi is divided into 9 Nava-amsha:
- 12 Rashi * 9 Nava-amsha = 108 Nava-amsha.
- Thus, the entire zodiac circle has 108 Nava-amsha.
Nakshatra System:
The Zodiac Circle:
- Similarly, the zodiac circle is a 360-degree circle.
Division into Nakshatras:
- The circle is divided into 27 equal parts, known as Nakshatras.
- Each Nakshatra covers 13 degrees 20 minutes of the circle.
Sub-Division of Each Nakshatra:
- Each Nakshatra is further divided into 4 equal parts, known as Padas (steps or quarters).
- Each Pada, therefore, covers 3 degrees 20 minutes.
Calculation:
- One Nakshatra = 13 degrees 20 minutes.
- One Pada = 1/4th of a Nakshatra.
- Therefore, one Pada = 13 degrees 20 minutes / 4 = 3 degrees 20 minutes.
Relationship with Nava-amsha:
- Notice that the length of one Pada (3 degrees 20 minutes) is the same as that of one Nava-amsha.
Total Divisions in the Zodiac Circle:
- Since there are 27 Nakshatras and each Nakshatra has 4 Padas:
- 27 Nakshatras * 4 Padas = 108 Padas.
- Thus, the entire zodiac circle has 108 Padas.
Summary:
- Both systems divide the zodiac circle into 108 parts.
- In the Rashi system, these parts are called Nava-amsha.
- In the Nakshatra system, these parts are called Padas.
- Each part (whether Nava-amsha or Pada) spans 3 degrees 20 minutes of the circle.
- Thus, one-ninth of a Rashi (Nava-amsha) is equivalent to one-fourth of a Nakshatra (Pada).
