Premanand Maharaj Ji
What conduct should I give up and take up at the start of bhakti?
Start with pure food
The first step in bhakti is to give up impure food: onion, garlic, meat, fish and eggs. If you eat very sattvic (pure, calm) food, fondness for Bhagwan awakens sooner within you.
When we take our first step in bhakti, we should first set right our diet. We should give up unfit food.
