Teaching
Instruction, Teachings, Lesson, Doctrine
noun
This is the noun version of the kanji teach. So it means teaching.
Since this word consists of a kanji with hiragana attached, you can bet that it will use the kun'yomi reading. You already learned this reading when you learned 教える, so you should be able to read this word as well.
「毎日全力で生きる」というのは、父からの教えです。
"Living every day to your fullest" is a teaching from my father.
それは、すばらしい教えですね。
It's such a great lesson, isn't it?
