Practice kung fu with an empty mind

Someone else told me that internal martial arts should be performed with an empty mind. Not with no mind, as that would mean unconsciousness. The empty mind is mind empty of thoughts and emotions. It is in a state of heightened alertness, it is not planning for the future and it is not analysing the past. It is focused on now. This allows you to be hundred percent in a present moment, ready for anything that comes your way. Practising in this way will develop maximum awareness, and responsiveness.
