76.The unwise deem love virtue only can sustain,

It also helps the man who evil would restrain.

77.As sun's fierce ray dries up the boneless things,

So loveless beings virtue's power to nothing brings.

78.The loveless soul, the very joys of life may know,

When flowers, in barren soil, on sapless trees, shall blow.

79.Though every outward part complete, the body's fitly framed;

What good, when soul within, of love devoid, lies halt and maimed?

80.Bodies of loveless men are bony framework clad with skin;

Then is the body seat of life, when love resides within.
