Six Favorable and Unfavorable Principles by Srila Rupa Goswami
The Six Favorable Principles
1. BEING ENTHUSIASTIC
Every endeavor in Krsna consciousness is performed with intelligence. The devotees are expert in engaging everything in Krsna's service. The practice of devotional service has nothing to do with selfish meditation, but means practical activity in spiritual life.
2. ENDEAVORING WITH CONFIDENCE
The devotee thinks "avasya raksibe Krsna": Krsna will certainly help and protect me, so that I can successfully execute my devotional service.
