If you continue to work in this writing and publishing of our literatures with steady enthusiasm and sincerity, your success in Krishna Consciousness is certain. Therefore to keep your spiritual strength, always observe the regulative principles strictly and chant at least sixteen rounds of beads daily without fail. This is essential for understanding our philosophy practically to advance in Krishna Consciousness. And we should always avoid mental speculations.
