Dhammapada Verse 3.1

Sanskrit Verse

स्पन्दनं चपलं चित्तं दुरक्ष्यं दुर्निवार्यम् । ऋजुं करोति मेधावी इषुकार इव तेजनम् ॥ १॥

Bhikkhu Ānandajoti's translation

Just as an arrow-maker straightens an arrow shaft, even so the discerning person straightens his mind—so fickle and unsteady, so difficult to guard and control.
