Solution focus and systemic thinking moved into psychotherapy at the end of the 1980s. Both were known in buddhist meditation and martial arts well before that.
In solution focussed thinking, we recognise ourselves through constant change rather than the meaning of a fixed being. We thus become free to experience change directly in our body, without analytic or verbal mediation. Such immediate experience is a core objective of zen buddhism.
Permanent change of our being is also an important concept in ancient greek philosophy, for example Heraklits "Panta Rei" ( "Everything is in flux.")
By adopting a solution focussed attitude, we give ourselves the freedom to assume new elements in our system and to let them adapt to each other. Assuming the other into one's own system is the spiritual basis for buddhist martial arts like Tai Chi, described systematically as soon as the 14th century or Aikido.
A powerful Meeting of Cultures
Martial Arts and Meditation are interested in very different topics than Psychotherapy. Their cultures are very different, too. Transferring their ideas to the field of Therapy was a great achievement. It has made Psychotherapy by far more effective.
