agnir vā eṣa vaiśvānaraḥ pañcamenir yat purohitas,
tābhī rājānam parigṛhya tiṣṭhati samudra iva bhūmim
ayuvamāry asya rāṣṭram bhavati,
nainam purāyuṣaḥ prāṇo jahāty,
ājarasaṃ jīvati, sarvam āyur eti,
na punar mriyate yasyaivaṃ vidvān brāhmaṇo rāṣṭragopaḥ purohitaḥ
kṣatreṇa kṣatraṃ jayati,
balena balam aśnute yasyaivaṃ vidvān brāhmaṇo rāṣṭragopaḥ purohitas
tasmai viśaḥ saṃjānate sammukhā ekamanaso yasyaivaṃ
vidvān brāhmaṇo rāṣṭragopaḥ purohitaḥ

viii. 25 (xl. 2.) The Purohita is Agni Vaiçvānara with five missiles; with these he keeps enveloping the king as the ocean the earth. His kingship perishes not in its youth, life leaves him not before his time, up to old age

he lives, he lives a full life, he dies not again, who has for Purohita to guard the kingdom a Brahman with this knowledge.

By the lordly power he conquereth the lordly power,
By might he attaineth might,
Who hath for Purohita to guard the kingdom
A Brahman with this knowledge,
For him are his people in harmony,
With one aspect and one mind,
Who hath for Purohita to guard the kingdom
A Brahman with this knowledge.
