The difference between Love and lust

Love according to Shakespeare

Love comforteth like sunshine after rain,

But Lust's effect is tempest after sun;

Love's gentle spring doth always fresh remain,

Lust's winter comes ere summer half be done.

Love surfeits not, Lust like a glutton dies;

Love is all truth, Lust full of forged lies.

Venus and Adonis
William Shakespeare
