Touch Treatment (Su)
At 3rd level, the mesmerist can help allies shake off harmful conditions—especially those that affect their minds—by channeling psychic energy through his healing hands. He can use touch treatment a number of times per day equal to 3 + his Charisma modifier. Using the ability is a standard action (or a swift action if the mesmerist uses it on himself ), and the mesmerist must be able to touch his target. He can remove one condition from one target each time he uses this ability. At 3rd level, he can remove any condition on the minor conditions list. At 6th level, he can remove any condition on the minor or moderate conditions list, and at 10th level, he can remove any condition on the minor, moderate, or greater conditions list.
If you cast it on yourself are you always considered to be touching yourself?
Are you asking if you can use the ability on yourself if you are paralyzed, or if you don't have a hand free? The consensus is "no." Paladin lay on hands is worded very similarly and definitely requires a free hand.
Not to say people won't try to split the language to argue the opposite.
Yes, and thanks for the clarification.
