1. By hearing, Krsna manifests Himself as the devotee desires

    O my Lord, Your devotees can see You through the ears by the process of bona fide hearing, and thus their hearts become cleansed, and You take Your seat there. You are so merciful to Your devotees that You manifest Yourself in the particular eternal form of transcendence in which they always think of You.
