Kapalabhati Pranayama is rapid exhalations with mental attention on the breathing. It removes toxins, causes lower energies to get translated into the higher ones and also reduces flab.

i agree...also a good way to fight diseases...many benefits...cleansing, invigorating, warming, prevents illness and allergies...kapala = skull ,bhati = light (implying perception, knowledge).We could say a lot about this kind of treatment/formula.
