Acharanga Bhasyam: Sūtras 69-70 : Manner Of Moving (For An Ascetic)

The self-restrained monk should concentrate his mind on his movement fix his vision on the path, contract his feet, inspecting creatures on the path, and walk carefully avoiding them.

Now the Sūtra explains the rule of physical movement: A person desirous of emancipation should move fully self-restrained; his mind should keep engaged on the movement, his awareness should be directed exclusively to the act of going; his eye should remain fixed on the path, he should move, properly inspecting the path, he should contract his feet^[1] when confronted witL living beings; he should carefully apprehend living creatures that may lie on the way. These are the five rules regarding self-restrained movement.

5.70 se abhikkamamāṇe paḍikkamamāṇe saṃkucemāṇe pasāremāṇe viṇiyaṭṭamāṇe saṃpalimajjhamāṇe.

The aspirant performs these acts fully self-restrained: moving forward and backward, contracting and expanding his body, ceasing from activities, and cleaning his body with a woolen brush.

The aspirant for emancipation sometimes moves forward, sometimes backward, sometimes contract his feet and arms, sometimes stretches them, sometimes he stops going and coming and wipes, with full restraint, the living beings crawling on his body, with woolen whisk.
