Humility and meekness are not appropriate when the acaryas are blasphemed
They do not know, however, that humility and meekness are appropriate when one’s own honor is insulted but not when Lord Viṣṇu or the ācāryas are blasphemed. In such cases one should not be humble and meek but must act.
CC Adi 10.85, Purport: The sahajiyas level three accusations against Srila Jiva Gosvami. This is certainly not congenial for the execution of devotional service. The first accusation concerns a materialist who was very proud of his reputation as a great Sanskrit scholar and approached Sri Rupa and Sanatana to argue with them about the revealed scriptures. Srila Rupa Gosvami and Sanatana Gosvami, not wanting to waste their time, gave him a written statement that he had defeated them in a debate on the revealed scriptures. Taking this paper, the scholar approached Jiva Gosvami for a similar certificate of defeat, but Jiva Gosvami did not agree to give him one. On the contrary, he argued with him regarding the scriptures and defeated him. Certainly it was right for Jiva Gosvami to stop such a dishonest scholar from advertising that he had defeated Srila Rupa Gosvami and Sanatana Gosvami, but due to their illiteracy the sahajiya class refer to this incident to accuse Srila Jiva Gosvami of deviating from the principle of humility. They do not know, however, that humility and meekness are appropriate when one's own honor is insulted but not when Lord Visnu or the acaryas are blasphemed. In such cases one should not be humble and meek but must act.
