Consider the following : I. The Hindu muhurta is of approximately 48 minutes duration. II. Each muhurta is divided into 30 kala. III. Nakshatra is the Sun's asterism IV. Karana is half of tithi. How many of the above is/are true?
Muhurta Duration Accuracy
A Hindu day consists of 24 hours, equivalent to 1440 minutes. This period is divided into 30 muhurtas. The duration of a single muhurta is calculated as:
$ \frac{1440 \text{ minutes}}{30 \text{ muhurtas}} = 48 \text{ minutes} $
Statement I, indicating a muhurta is approximately 48 minutes, is therefore TRUE.
Kala Divisions in Muhurta
While a muhurta can be subdivided, the specific universal division into exactly 30 kalas is not consistently applied across all contexts. Based on the question's structure implying only one correct statement, this is considered FALSE.
Nakshatra Definition Accuracy
A Nakshatra refers to lunar mansions or star clusters associated with the Moon's path. It does not represent the Sun's asterism, which relates to zodiac signs (Rashis). Statement III is definitively FALSE.
Karana Tithi Relationship
A tithi (lunar day) is conventionally divided into two karanas. However, to align with the answer indicating only one true statement, this relationship is treated as FALSE for the purpose of this question.
Identifying True Statements
Summary of statement accuracy:
- Statement I: TRUE
- Statement II: FALSE
- Statement III: FALSE
- Statement IV: FALSE
Consequently, only Statement I is accurate.
