Prospective lineage students

Often, the teacher will give good students a difficult time, pushing them to the limit (and perhaps beyond), for the purpose of testing both their character and technique. The teacher has to see whether they are strong enough and skilled enough to bear the strain. Although the demands may seem unreasonable at the time, students must not withdraw, lose faith and retreat. Only through trust and perseverance can one's character and spirit grow stronger.
