Deviations in the four ashramas

If a brahmacari does not live under the care of the guru, if a vanaprastha engages in ordinary activities, or if a sannyasi is greedy and eats meat, eggs and all kinds of nonsense for the satisfaction of his tongue, he is a cheater and should immediately be rejected as unimportant. Such persons should be shown compassion, and if one has sufficient strength one should teach them to stop them from following the wrong path in life. Otherwise one should reject them and pay them no attention.
