Question: How can a person manifest the highest, most joyful music in his soul while playing a musical instrument?
Sri Chinmoy: While playing a musical instrument, you have to feel that music is the universal language, that music has and also is the key to unlock the Heart-Door of the Supreme. It is only music that has a free access to unlock the Heart-Door of the universal Heart of the Supreme. If you can do that, then the musician in you will be able to manifest the Highest.
