The only process for perceiving Krishna and His name, qualities, form is our sincere service attitude with our senses. Beginning from the tongue, all our senses are practically led by the tongue sense, whose business is to vibrate and to taste. If we can change the materialistic nature of the tongue, by changing of taste and vibration, then automatically the other senses become purified. And we can render service to Krishna with purified senses. As such we should try to chant and eat Krishna prasadam as much as possible.
