6. “Again, bhikkhus, when walking, a bhikkhu understands: ‘I am walking’;
when standing, he understands: ‘I am standing’;
when sitting,  he understands: ‘I am sitting’;
when lying down, he understands: ‘I am lying down’;
or he understands accordingly however his body is disposed.
7. “In this way he abides contemplating the body as a body internally, externally, and both internally and externally … And he abides independent, not clinging to anything in the world.
That too is how a bhikkhu abides contemplating the body as a body.
