Dhammapada · 21.16

Ekāsanaṃ ekaseyyaṃ, eko caramatandito;Eko damayamattānaṃ, vanante ramito siyā.

Ekasanam ekaseyyam, eko caramatandito; Eko damayamattanam, vanante ramito siya.

Sitting alone, sleeping alone, walking alone unwearied, alone subduing oneself — let one delight at the forest's edge.
