The elder Subhuti said to the Buddha,” It’s very rare, World Honored One! How well the Tathagata protects and thinks of all Bidhisattvas! How well He instructs all the Budhisattvas! World Honored One! When virtuous men or women develop the supreme-enlightenment mind, how should their mind aside and how should they be subdued?” However, having Budhicitta means the consciousness of the heart. “How should their mind aside?” is the thoughtless, non-abidance, or selflessness. “How should they be subdued?” is the overthrowing of the first heart (bad habits) and the creation of the new heart (pure heart). The heart is the core of our lives the hub which we should surpass. To digest the words of those classical books, we have to not only know our true heart but also examine our own feelings about people and things. When facing the difficulties, we may try our best to adjust our attitudes. By doing these, we hope we can have the strongest power to deal with everything in our lives. The ambition of education focuses on guiding students to understand themselves, accept themselves, and achieve themselves. And it helps them to own the practical lives. Master Xiao-Yun mentioned in the enlightenment education, “Do you realize what you need most in your life? Do you know what you treasure most in surviving? Nothing but the way you feel comfortable and the harmony. We experience the unbearable lightness or heaviness of being all the time. The most important and cherish thing is we know how to feel peaceful, get along with ourselves, and balance on everything. Math teaching is math about the process of math cogitation. The process of students' learning math focuses on letting them build the process of the cognitive structure in their mind. The essay tries to think how a teacher adjusts his/her own teaching mindset and methods to master math teaching by the inclusion of the teaching principles and life wisdoms from “They should develop a mind which does not abide in anything.” of the Diamond Sutra as reflections. Teachers master their own math teaching to let students not be afraid of math and develop the right learning attitudes. By the process of exploring questions, organizing and summarizing, the interpretations of their ideas and finding the answers, students develop their thinking. This will open their mind. They can apply this in their lives and enjoy the happiness of growing.
