Monk Stance action / maintaining the action

[no good scallywag]

If a Monk enters a stance with an action, does he have to then again, on the next round, enter the stance again at the cost of an action?

Does moving change the stance?

[cithis]

A stance is maintained automatically as long as you choose to maintain it. It costs no actions to keep active, however it cannot be used outside of an encounter.

To expand on that, the only things that kick you out of a stance are changing into another one, getting knocked unconscious or leaving encounter mode. For stances that have specific requirements, you also need to keep fulfilling them or leave the stance. Other than that, you can move and use other actions all you want and stay in stance.
