Even the very sound of the holy name of Lord Krishna or Rama can at once surcharge the atmosphere spiritually.
The Real Art of Living
When we hear about the Lord, we should hear with a spirit to serve the Lord. When we chant his names, we should chant so that He is pleased to hear us chanting. That is the beauty of life, the real art of living.
This is the only medicine
Prabhupada: Ceto-darpana-marjanam [Cc. Antya 20.12]. And then bhava-maha-davagni… Then his material pangs will be over. This is the only medicine. Therefore chant Hare Krsna. Some way or other, let them have the chance of hearing, and then it will act as medicine

Good Signs in Chanting
It is the aspiration of a devotee that while he chants the Hare Krsna maha-mantra his eyes will fill with tears, his voice falter and his heart throb. These are good signs in chanting the holy name of the Lord.
