Your perfect focus allows you to recover quickly from injury.
In addition, when you are at 0 or fewer hit points you can spend 1 point from your ki pool to heal a number of hit points equal to your Wisdom modifier. This can be done once per round and does not require an action. When you receive an effect that cures hit point damage, including mundane healing such as first aid with the Heal skill as well as magical healing, you can spend 1 point from your ki pool as an immediate action to increase the healing you receive by a number of hit points equal to your Wisdom bonus; this curing applies to both lethal and nonlethal damage if you have both types.
