10.3.44

purohitapuruṣāḥ kṛtyābhicāraṃ brūyuḥ, yantrikavardhakimauhūrtikāḥ svakarmasiddhim asiddhiṃ pareṣām //

Soothsayers and court bards should describe heaven as the goal for the brave and hell for the timid; and also extol the caste, corporation, family, deeds, and character of his men. The followers of the priest should proclaim the auspicious aspects of the witchcraft performed. Spies, carpenters and astrologers should also declare the success of their own operations and the failure of those of the enemy.
