Caitanya Caritamrta Antya 6.279

TRANSLATION

When one accepts an invitation from a person contaminated by the material mode of passion, the person who offers the food and the person who accepts it are both mentally contaminated.

PURPORT

Srila Bhaktivinoda Thakura says that there are three varieties of invitations — those in the mode of goodness, those in passion and those in ignorance. An invitation accepted from a pure devotee is in the mode of goodness, an invitation accepted from a person who is pious but materially attached is in the mode of passion, and an invitation accepted from a person who is materially very sinful is in the mode of ignorance.
