Krishna Kirtana is not for earning livelihood. Krishna Kirtana is not meant for entertaining the public for demonstration of arts.

It is dynamic service to the Lord. We do not therefore mind so much about the artistic presentation of Krishna Kirtana but we want to see how much a devotee is satisfying the Supreme Will.
- Correspondence, Calcutta, December 1967

 On the Absolute world there are no such relativities as success and failure. The one thing in the Absolute world is to serve Krishna. Don't care for the result. Krishna must know that we are working very seriously and that is our success of life.
- Correspondence, San Francisco, December 1967

Devotional service means to apply one's energy in the service of Krishna. That is the instruction of the Bhagavad-gita… we cannot understand about Krishna with our limited potency and senses, but if we engage ourselves in the service of the Lord, He will reveal Himself to the faithful servitor… The more we learn about Krishna from the authoritative sources, the more we can be attached in Krishna Consciousness.
- Correspondence, San Francisco, December 1967

  Vedanta means ultimate knowledge. Knowledge is never perfect unless one comes to the point of understanding Krishna.

To remain in Krishna Consciousness is actual understanding of Vedanta.
