दूष्यमहामात्रं वा सूदो भक्षकारो वा ते शोभनः इति स्तवेन भक्ष्यभोज्यं याचेत बहिर्वा क्वचिदध्वगतः पानीयम् ॥ कZ_०५.१.३० ॥
dūṣyamahāmātraṃ vā sūdo bhakṣakāro vā te śobhanaḥ iti stavena bhakṣyabhojyaṃ yāceta bahirvā kvacidadhvagataḥ pānīyam
A cook or food-preparer should, by flattering words like ‘you are admirable,’ solicit edible food and drink from a targeted high official; or, when the target is outside somewhere on the road, solicit drinking water.
Travel reduces controlled safeguards; requesting water is socially normal and lowers suspicion, enabling a deniable delivery method.
