Examine your environment

Stand in the sun; that is, take up an attitude with the sun behind you.
If the situation does not allow this, yo umust try to keep the sun on
your right side. In buildings, you must stand with the entrance behind
you or to your right. Make sure that your rear is unobstructed, and that
there is free space on your left, your right side being occupied with
your sword attitude. At night, if the enemy can be seen, keep the fire
behind you and the entrance to your right, and otherwise take up your
attitude as above. You must look down on the enemy, and take up your
attitude on slightly higher places. For example, the Kamiza in a house
is thought of as a high place.
