Confucius: "no Offsprings Students is a very big sin." So teach later generations to upkeep the Zen Jedi Spirit.
Know how to teach.
Empathize from the student perspective.
Dare to teach.
The you smoke. The you father tells your children not to smoke. Is it possible? Lead by example first. Then instructions.
Do not let them feel like stupid idiots.
Your first few students not have the effect. After that, Super Teachings.
You give many water (love) & little fertilizer (instructions). But you do not pull them (force them to learn too fast). Meng Zi Scripture. 四书孟子。 "You just encourage them to grow."
Teachings are 100% Role Model + 1% Words. JESUS CHRIST: "be the Light on the Hill Top." Confucius: "it is a shame. If you cannot do it, & tell Others to do it."
Teaching is a Way to pass down Our Knowledges & Wisdom down to the Later Generations. Just in case we die in action. We also need to train New Jedi with all Our Might. We do not know what to expect in the future.
