Śrīla Bhaktivinoda Ṭhākura 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.
