Sensei (先生): a Master that is willing to teach.
Literally:
Sen: Further, Forward
Sei: Life;
'The one that brings others forward in life'
Although it is tempting to translate 'Sensei' as
Teacher, there is a subtle difference due to the differnces in the Western and Japanese teaching systems.
It is the Sensei's greatest honor when his pupil becomes better than the master. To understand this difference please read about the
ShuHaRi learning system
