OK! Just to illustrate that Krishna too knows that "a spoonful of sugar helps the medicine go down..."
"Recite the name of Krishna; think of him; offer flowers; and all obstacles will vanish. All sins committed before taking Refuge with Him,as well those unwittingly
accruing after Surrender (Saranagati) will perish. The Purva Agha (earlier sins) will be burnt to ashes like cotton bales in a fire;and the Uttara Agha (Subsequent Sins) will not stick to the person like drops of water to a lotus leaf.
Milk is both a pleasurable food as well as a medicine to cure bile. The same is the case with Him. (Maruttuvanai ninra mamanivanna)"
(from Sri Bhuvarahacharya's commentary on Tiruppavai)
Krishna is the medicine we need to cure us of our paap and our attachment to the material world. Good thing He's sweet, too. That's His kindness.
