“ Xin (trustworthiness)--The four virtues of Ren (benevolence), Yi (righteousness), Li (propriety) and Zhi (wisdom) are at the four directions while trustworthiness is in the middle. The centre's attribute is the element earth. All living things cannot flourish without the earth just as the four virtues cannot be established without trustworthiness. If one can keep it vigilantly without losing it, one will have many blessings for a long time to come.”
