Whether you are walking, standing, sitting, or lying down, speaking or remaining silent —no matter what you are doing— always remain mindful of the Buddha in your heart, just as a starving person thinks of food or a thirsty person thinks of water.
You may lower your head and raise your arms, or raise your voice and recite the Name. Although your outward actions may differ, always keep that remembrance in mind. Keep it continuously from moment to moment, and never forget it, no matter whether you are awake or asleep. —Genshin
