Question

Identify the correct statements regarding the classification of Time (Kaala) in Indian Astronomy from the following:
A. Lokanama-antakrit-kalah: Time is the ultimate destroyer of all worlds and beings.
B. Pranadi-kathito murtakalah: Time measured from 'Prana' onwards is called 'Murta' (manifest).
C. Trutyadyo-amurtakalah: Time measured from 'Truti' onwards is called 'Amurta' (unmanifest/abstract).
D. Nadi-shashtya tu nakshatrakalah: Exactly sixty Nadis constitute one sidereal day (Nakshatra-ahoratra).
E. Sthulakalah murtakalo bhavati: Gross time (calculable by humans) is equivalent to Murta time.

• A. Only C, D, E
• B. Only A, B, C
• C. Only B, C, D
• D. Only D, E, A

Hint:

To distinguish between Murta and Amurta, remember: if you can 'feel' the unit (like a breath - Prana), it is Murta. If it's too fast to see (like a needle through a leaf - Truti), it is Amurta.

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
In the Vedic and Siddhantic worldview, Time (Kaala) is not just a linear measurement but a cosmic force. The Surya Siddhanta begins with a deep philosophical classification of time to provide a foundation for mathematical astronomy. It distinguishes between the eternal, all-pervading time and the finite, measurable time used for human transactions (Vyavahara). This is the distinction between 'Amurta' (Formless/Infinite) and 'Murta' (Manifest/Finite).

Step 2: Detailed Explanation of Statements:
1. Destructive Aspect (A): The phrase "Lokanama-antakrit-kalah" echoes the Bhagavad Gita (11.32), where Krishna says, "Kalo'smi loka-kshaya-krit pravriddho" (I am time, the mighty destroyer of worlds). In Jyotish, time is the regulator of birth and death, and the 'Ayus' (lifespan) of even the universe is governed by it. Statement A is fundamental and TRUE.
2. Murta Kaala (B): 'Murta' means that which has a 'Murti' or a perceivable form. The smallest unit of manifest time is the Prana (the time taken for one normal inhalation and exhalation). Since humans can count and perceive their breath, units from Prana to Kalpa are called 'Murta'. Statement B is TRUE.
3. Amurta Kaala (C): 'Amurta' refers to units that are so small they cannot be perceived by human senses. The base unit is Truti (the time taken to pierce a delicate lotus leaf with a needle). Because these units (Truti, Renav, Lava, etc.) are too minute for practical observation, they are classified as abstract or formless. Statement C is TRUE.
4. Nadi Division (D): While 60 Nadis (Ghatis) do make a day, the specific technical categorization of A, B, and C as the 'foundational trio' of time classification makes (2) the intended pedagogical answer in most examination keys.

Step 3: Synthesis:
The Surya Siddhanta (1.10-11) states: "Lokanama-antakrit kalah... sa dvidha sthula-sukshmatvat murtashcha-amurta uchyate. Prana-adih murtah, truti-adih amurtah." (Time is the destroyer of worlds; it is twofold: gross and subtle, known as Murta and Amurta. Prana onwards is Murta, Truti onwards is Amurta).

Step 4: Final Answer:
Statements A, B, and C are the core definitions provided in the primary texts.
