In an order given to agnīdhra priest, the first syllable as well as the succeeding syllable is pluta.,
In a Yajna, the principal priests (rtvij) are four Adhvaryu, Udgata, Hota, Brahma. Every one of these has three subordinate priests (rtvij) under them: as shown below.
- Adhvaryu: - (Yajur) - Pratiprasthata - Nestha 6.4.11 - Unneta.
- Udgata - (Saman) - Prastota - Pratiharta - Subrahmanya.
- Hota (Rig) VI. 4. 11. - Maitra - varuna - Achchhavak - Pota 6.4.11.
- Brahma (Atharvan) - Brahmanachhansi - Agnidhra - Gravastuta 3.2.177.
The duty of Agnidhra is to kindle the sacrificial fire. In a summons or call (प्रेषण) made by the Adhvaryu, who is the Director of ceremonies, to the Agnidhra to perform the functions of Agnidh, both syllable become pluta.
The word अग्नीत् प्रेषण is a compound = अग्नीधः प्रेषणम् \a call or summon relating to Agnidh duty.\
Thus आ ३ श्रा ३ वय, ओ ३ श्रा ३ वय ॥ The pluta takes place only in these examples; therefore, not here, as अग्नीदग्नीन् विहर; यर्हि स्तृणीहि ॥ Some, therefore, read the anuvritti of the word विभाषा from the next sutra, into this, and would have it an optional rule, of fixed jurisdiction (vyavasthita vibhasha). Others say \all pluta rules are optional\ (सर्व एव प्लुतः साहसमनिच्छता विभाषा विज्ञेयः) In उद्धर ३ उद्धर, अभिहर ३ अभिहर, there is Vedic diversity.
The words 'relating to sacrificial work' (यज्ञकर्मणि) are understood here also. Therefore not in ओ श्रावय ॥,
