We live in two worlds. one is the outer world of "what". It is about appearances and forms that captivate our eyes. This world can be designed, presented and manipulated as wished. However, hidden from our view, there is another world of "how". how things actually function, their composition, the relation between one and all, partial and whole.This world is not so visible to the eye. it is sometimes puzzling, sometimes intriguing, but this world of how contains the secret of success: how things move and change. that is what the ODHA approach stands for. It's an invitation to the curious and the restless to DIVE DEEP into the world of HOW-  creating from a common place: the Open Heart.
