“Ethical discipline is the water to wash away the stains of misdeeds. It’s the ray of moonlight to cool the scorching heat of disturbing emotions. (With it,) you shine out amidst the nine kinds of beings, like a Mount Meru. By its power, you bend all beings (to your positive influence) without (need for) mesmerizing stares. Realizing this, the hallowed beings safeguard, as they would their eyes, the vowed discipline that they have take on purely. The ennobling, impeccable Lama has practiced like that. Let me, too, who strives for liberation, cultivate myself in the same way.”
