One of the most important instructions by Sri Caitanya Mahaprabhu regarding regular Vaisnava behavior is that a Vaisnava should be tolerant like a tree and submissive like grass.

"One should chant the holy name of the Lord in a humble state of mind, thinking oneself lower than the straw in the street; one should be more tolerant than a tree, devoid of all sense of false prestige and should be ready to offer all respect to others. In such a state of mind one can chant the holy name of the Lord constantly." Nevertheless, the author of these instructions, Lord Caitanya Mahaprabhu, did not tolerate the misbehavior of Jagai and Madhai. When they harmed Lord Nityananda Prabhu, He immediately became angry and wanted to kill them, and it was only by the mercy of Lord Nityananda Prabhu that they were saved. One should be very meek and humble in his personal transactions, and if insulted a Vaisnava should be tolerant and not angry. But if there is blasphemy against one's guru or another Vaisnava, one should be as angry as fire. This was exhibited by Lord Caitanya Mahaprabhu. One should not tolerate blasphemy against a Vaisnava but should immediately take one of three actions. If someone blasphemes a Vaisnava, one should stop him with arguments and higher reason. If one is not expert enough to do this he should give up his life on the spot, and if he cannot do this, he must go away. While Caitanya Mahaprabhu was in Benares or Kasi, the Mayavadi sannyasis blasphemed Him in many ways because although He was a sannyasi He was indulging in chanting and dancing. Tapana Misra and Candrasekhara heard this criticism, and it was intolerable for them because they were great devotees of Lord Caitanya. They could not stop it, however, and therefore they appealed to Lord Caitanya Mahaprabhu because this blasphemy was so intolerable that they had decided to give up their lives.
