Based on Bhagavad Gita Chapter 18, Text 37
As devotees who wish to rise from the material level to the spiritual level, we often face the question, “How do I sustain myself during the phase when I have to abstain from material enjoyment but can’t yet experience spiritual fulfillment?”

By thus facilitating us to see beyond appearances to consequences, conviction enables us to stay away from anti-devotional material indulgences.
