“When one eats food offered by a materialistic man, one’s mind becomes contaminated, and when the mind is contaminated, one is unable to think of Kṛṣṇa properly.
Śrīla Bhaktisiddhānta Sarasvatī Ṭhākura suggests that people who are materialistically inclined and sahajiyās, or so-called Vaiṣṇavas who take everything very casually, are both viṣayīs, or materialists. Eating food offered by them causes contamination, and as a result of such contamination, even a serious devotee becomes like a materialistic man. There are six kinds of association—giving charity, accepting charity, accepting food, offering food, talking confidentially and inquiring confidentially. One should very carefully avoid associating with both the sahajiyās, who are sometimes known as Vaiṣṇavas, and the non-Vaiṣṇavas, or avaiṣṇavas. Their association changes the transcendental devotional service of Lord Kṛṣṇa into sense gratification, and when sense gratification enters the mind of a devotee, he is contaminated. The materialistic person who aspires after sense gratification cannot properly think of Kṛṣṇa.
