कदाचिद्द् हि प्रदुष्टस्य नाधिगम्येत भेषजम् ॥ कZ_०१.१०.१८च्द् ॥
kadācidd hi praduṣṭasya nādhigamyeta bheṣajam
For one who has become corrupted, a remedy may sometimes not be obtainable (i.e., reform may no longer be possible).
Design systems to prevent corruption early (screening, monitoring, rotation), because once deeply compromised an official may resist correction and endanger the state.
