Suppose a mendicant has got rid of desire and ill will while walking, and has given up dullness and drowsiness, restlessness and remorse, and doubt. Their energy is roused up and unflagging, their mindfulness is established and lucid, their body is tranquil and undisturbed, and their mind is immersed and unified in samādhi. Such a mendicant is said to be ‘keen and prudent, always energetic and resolute’ when walking.

Suppose a mendicant has got rid of desire and ill will while standing …

sitting …

or when lying down while awake, and has given up dullness and drowsiness, restlessness and remorse, and doubt. Their energy is roused up and unflagging, their mindfulness is established and lucid, their body is tranquil and undisturbed, and their mind is immersed and unified in samādhi. Such a mendicant is said to be ‘keen and prudent, always energetic and resolute’ when lying down while awake.

Carefully walking, carefully standing, carefully sitting, carefully lying; a mendicant carefully bends their limbs, and carefully extends them.

Above, below, all round, as far as the planet extends; they scrutinize the rise and fall of phenomena such as the aggregates.

Training in what leads to serenity of heart, always staying mindful; they call such a mendicant ‘always determined’.”
