Anyone serious about progressing in Krishna Consciousness must avoid the following four sinful activities:

1. Eating meat, fish or eggs. These foods are saturated with the modes of passion and ignorance and therefore cannot be offered to the Lord.

2. Gambling. Gambling invariably puts one into anxiety and fuels greed, envy, and anger.

3. The use of intoxicants. Drugs, alcohol, and tobacco, as well as any drinks or foods containing caffeine, cloud the mind, overstimulate the senses, and make it impossible to understand or follow the principles of bhakti-yoga.

4. Illicit sex. This is sex outside of marriage or sex in mar¬riage for any purpose other than procreation.
