Understanding Pratyāhāra in Aşhțādhyāyi
Pāṇini's Aşhțādhyāyi is a foundational text in Sanskrit grammar. It uses a system of mnemonic rules called Pratyāhāra (प्रत्याहार) to refer to groups of sounds (vowels and consonants) efficiently. These Pratyāhāras are derived from the Śivasūtras (शिवसूत्र), a list of 14 sutras that enumerate the sounds of Sanskrit, often called the 'varnasamāmnāya' (वर्णनाम ्न ्न ्न).
Deriving the 'अट्' Pratyāhāra
The specific Pratyāhāra in question is 'अट्' (Aṭ). This term is formed by taking the first sound $\textit{अ}$ (a) and the final sound $\textit{ट्}$ (ṭ) from the relevant sequence in the Śivasūtras. The sounds included are those starting from $\textit{अ}$ up to $\textit{ट}$, excluding the final $\textit{ट}$ itself (as it's an 'it' sound, or marker).
To determine the sounds included in 'अट्', we examine the beginning parts of the Śivasūtras:
| Sūtra Number | Sanskrit Text | Transliteration | Sounds |
|---|---|---|---|
| 1 | $\textit{अ}$ $\textit{इ}$ $\textit{उ}$ $\textit{ण्}$ | a i u ṇ | $\textit{अ}$, $\textit{इ}$, $\textit{उ}$ |
| 2 | $\textit{ए}$ $\textit{ओ}$ $\textit{ङ्}$ | e o ṅ | $\textit{ए}$, $\textit{ओ}$ |
| 3 | $\textit{ऐ}$ $\textit{औ}$ $\textit{च्}$ | ai au c | $\textit{ऐ}$, $\textit{औ}$ |
| 4 | $\textit{ह}$ $\textit{य}$ $\textit{व}$ $\textit{र}$ $\textit{ट्}$ | ha ya va ra ṭ | $\textit{ह}$, $\textit{य}$, $\textit{व}$, $\textit{र}$ |
The 'अट्' Pratyāhāra starts with the sound $\textit{अ}$ (a) from Sūtra 1 and ends with the sound $\textit{ट्}$ (ṭ) from Sūtra 4. According to the Pratyāhāra rule, all sounds from the starting sound up to and including the 'it' sound are grouped, but the 'it' sounds themselves ($\textit{ण्}$, $\textit{ङ्}$, $\textit{च्}$, $\textit{ट्}$) are only indicators and not part of the resulting group.
Therefore, the complete set of sounds included in the 'अट्' Pratyāhāra is:
- $\textit{अ}$ (a)
- $\textit{इ}$ (i)
- $\textit{उ}$ (u)
- $\textit{ए}$ (e)
- $\textit{ओ}$ (o)
- $\textit{ऐ}$ (ai)
- $\textit{औ}$ (au)
- $\textit{ह}$ (h)
- $\textit{य}$ (y)
- $\textit{व}$ (v)
- $\textit{र}$ (r)
Analysing the Options for 'अट्' Pratyāhāra
Let's check each of the given options against the list of sounds that belong to the 'अट्' Pratyāhāra:
- Option 1: $\textit{इ}$ (i) - This sound is the second vowel listed in the first Śivasūtra and is clearly part of the 'अट्' Pratyāhāra.
- Option 2: $\textit{क}$ (ka) - The sound $\textit{क}$ belongs to the 'क्' group, which appears much later in the Śivasūtras (Sūtra 11: $\textit{क्}$ $\textit{ल्}$). It does not fall within the range defined by the 'अट्' Pratyāhāra.
- Option 3: $\textit{ह}$ (h) - This consonant is the first sound in the fourth Śivasūtra ($\textit{ह}$ $\textit{य}$ $\textit{व}$ $\textit{र}$ $\textit{ट्}$) and is therefore included in the 'अट्' Pratyāhāra.
- Option 4: $\textit{र}$ (r) - This consonant is listed in the fourth Śivasūtra ($\textit{ह}$ $\textit{य}$ $\textit{व}$ $\textit{र}$ $\textit{ट्}$) and is also part of the 'अट्' Pratyāhāra.
Conclusion on 'अट्' Pratyāhāra Membership
From the analysis, the sounds $\textit{इ}$, $\textit{ह}$, and $\textit{र}$ are all included in the 'अट्' Pratyāhāra as defined by Pāṇini's Aşhțādhyāyi and the Śivasūtras. The sound $\textit{क}$ is not part of this group.
Therefore, $\textit{क}$ is the sound that is not included in the 'अट्' Pratyāhāra.
