Srutakirti Dasa: Once a devotee asked Srila Prabhupada: 'Srila Prabhupada, it's very difficult to control my mind when I chant. It wanders.'
Srila Prabhupada: "So what is the controlling of mind? You have to chant and hear. That is all. You have to chant with your tongue, and the sound you hear. What is the question of mind?"
