Srimad Bhagavatam Canto 10, Chapter 33, Text 36

SB 10.33.36

anugrahaya bhaktanam
 manusam deham asthitah
bhajate tadrsih krida
 yah srutva tat-paro bhavet
 
Translation: 
 
When the Lord assumes a humanlike body to show mercy to His devotees, He engages in such pastimes as will attract those who hear about them to become dedicated to Him.
 
Purport: 
 
Srila Jiva Gosvami explains in this connection that when Lord Krsna descends to this world in His original two-handed form, out of kindness He manifests that form in a way His devotees conditioned in human society can perceive and understand. Thus here it is stated, manusam deham asthitah: “He assumes a humanlike body.” Srila Visvanatha Cakravarti Thakura glorifies the Lord’s conjugal pastimes, stating that these romantic affairs have an inconceivable spiritual potency to attract the polluted heart of conditioned souls. It is an undeniable fact that any pure- or simple-hearted person who hears narrations of the loving affairs of Krsna will be attracted to the lotus feet of the Lord and gradually become His devotee.
