When a good thing is given to one, the mind is pleased, but soon after settles down into its previous state; if some bitter medicine is forced upon it, it revolts but almost immediately reverts to its normal state. This shows that both the pleasures and pains of this world are transient.

A few minutes ago you ate chocolates with relish, but that enjoyment has now become a thing of the past and has resulted in nothing. So with all pleasures and pains. One of the greatest enjoyments of the carnally-minded is sexual intercourse. But its pleasure lasts only so long as the intercourse lasts. No sooner does the intercourse come to an end than the pleasure ends.

Compare the transiency of earthly pleasures with the permanency of spiritual bliss, and you will find the difference between the two.
