Book 4; Universal Love I
Mozi
“When feudal lords love one another there will be no more war; when heads of houses love one another there will be no more mutual usurpation; when individuals love one another there will be no more mutual injury. When ruler and ruled love each other they will be gracious and loyal; when father and son love each other they will be affectionate and filial; when older and younger brothers love each other they will be harmonious. When all the people in the world love one another, then the strong will not overpower the weak, the many will not oppress the few, the wealthy will not mock the poor, the honoured will not disdain the humble, and the cunning will not deceive the simple. And it is all due to mutual love that calamities, strife, complaints, and hatred are prevented from arising. Therefore the benevolent exalt it.”

Fruits of Solitude (1682), Part I
Context: Love is indeed Heaven upon Earth; since Heaven above would not be Heaven without it: For where there is not Love; there is Fear: But perfect Love casts out Fear. And yet we naturally fear most to offend what we most Love. What we Love, we'll Hear; what we Love, we'll Trust; and what we Love, we'll serve, ay, and suffer for too. If you love me says our Blessed Redeemer) keep my Commandments. Why? Why then he'll Love us; then we shall be his Friends; then he'll send us the Comforter; then whatsover we ask, we shall receive; and then where he is we shall be also, and that for ever. Behold the Fruits of Love; the Power, Vertue, Benefit and Beauty of Love! Love is above all; and when it prevails in us all, we shall all be Lovely, and in Love with God and one with another.

“When one heart opens to another heart, it usually results in love.”
