5.5.2

ābhyantaraṃ bāhyaṃ guhyaṃ prakāśyam ātyayikam upekṣitavyaṃ vā kāryaṃ "idam evam" iti viśeṣayec ca //

WHEN employed as a minister, he (the courtier) shall show the net revenue that remains after all kinds of expenditure are met with. He shall also give the exact particulars--as this is thus--of whatever work is external, internal, secret, open, costly, or negligible. He shall follow the king in his pursuits after hunting, gambling, drinking, and sexual pleasures. Ever attending upon the king, he shall, by flattery, endeavour to arrest his fall into evil habits and save him from the intrigues, plots. and deceptions of enemies. He shall also endeavour to read the mind and appearance of the king.
