Source: BG 3.29 Purport
Men who are ignorant cannot appreciate activities in Kṛṣṇa consciousness, and therefore Lord Kṛṣṇa advises us not to disturb them and simply waste valuable time. But the devotees of the Lord are more kind than the Lord because they understand the purpose of the Lord. Consequently, they undertake all kinds of risks, even to the point of approaching ignorant men to try to engage them in the acts of Kṛṣṇa consciousness, which are absolutely necessary for the human being.
