You are asked to understand the pain of choosing between worldly success and your conscience. It is natural to feel that even poverty is better than gaining wealth through actions that violate your dharma, or moral duty. True peace cannot come from material pleasures, which are just temporary traps of maya, the illusion of worldly happiness.
Translation
2.5 It is better even to live on a beggar's fare in this world than to slay these most venerable teachers. If I should slay my teachers, though degraded they be by desire for wealth, I would be enjoying only blood-stained pleasures here.
