You utilize biokinetic techniques when you gain your focus.
Prerequisites
Constitution 13, Psionic Meditation.
Benefit
You may choose to gain temporary hit points equal to 1/2 your manifester level whenever you gain your psionic focus. These temporary hit points last for until you expend or lose your psionic focus. Temporary hit points from this feat do not stack with themselves if you are able to gain more than one psionic focus.
