You must have a clear hearty and a totally open mind to receive Systema. Noble sounding
words, but what does having an empty cup mean?
You have to be able to let go of everything you know about Systema if you wish to learn from a great teacher. How can a student learn form a teacher when the student already believes they know the lesson? In the beginning its normal to cling to 'what you know', but Systema is changing. It moves, it transforms itself, it's evolving constantly.
