This i have tried to do with the person's shadow 'weighing them down' through psionic sciences, but, i have now decided that it should be available for people that do not understand science, although it will most probably be 'weaker.'
The best way i think to do this without your own manna, is to make them 'stiff.' have you ever been so angry you couldn't do anything, except clutch at your head and double over a little bit? happens to some people, people that are used to stress, so, it can happen to anybody if you ask me.
This would be activity in their muscles, yes? that would mean stressing their muscles out so much they cannot 'unclench.' that would mean you want to make them angry - fire of course.
So, you should clam yourself down, and, wave your hand in a backhand motion to 'wave them away.' then, you should say something soothing, like, "i hope you are happy." all the while doing that, you need to focus your faery affinity to their minds, and make them being 'booed' or something - like by a football stadium. this should make them stiff or pass out.
