Anger

धन्यास्ते पुरुषश्रेष्टाः ये बुद्ध्या कोपमुत्थितम्।

निरुन्धन्ति महात्मानो दीप्तमग्निमिवांभसा॥३

क्रुद्धः कार्यं न कुर्यात्क क्रुद्धो हन्यात् गुरूनपि।

क्रुद्धो परुषया वाचा नरः साधूनधिक्षिपेत्॥४

वाच्यावाच्यं प्रकुपितो न् विजानाति कर्हिचित्।

नाकार्यमस्ति क्रुद्धस्य नावाच्यम् विद्यते क्वचित्॥५

यः समुत्पतितं कोपं क्षमयैव निस्रस्यति।

यदोरग्स्त्वचम् जीर्णाम् स वै पुरुष उच्यते॥६

Hanuaman reached Lanka and successfully met sita and conveyed to her the well-being of Rama. Then he fought with demons and especially Indrajit and was captured and taken to the court of Ravana. The angry Ravana first decided to decapitate him but following the sage advice of his brother Vibhishana, desisted from killing of an emissary. But it was decided that the monkey's tail would be set on fire. But the fire at the tip of the tail of Hanuman did not burn him because of the blessings of  Sita and also the god of fire and air. Then he jumped out and started setting fire on all parts of Lanka. For a moment he forgot, in his rage that Sita was also living in Ashoka Vanika a part of Lanka and so the action would inundate that place also;  He is remorseful .He exclaims "Indeed greatly fortunate are those great persons who simply put a stop to anger using their intellect like dousing fire with a stream of water. 

What is impossible for a man in anger not to do? The enraged man may kill his preceptors and parents.  

The man with blind anger will insult even the greatest of men with very dirty and cruel words.  

The man in a fit of anger does not know what he is talking and what he should not talk.  

For an man in rage there is nothing that is beyond his misdeeds, and there is no control over the foul words he will use.  

A man who throws away the anger generated in him with the weapon of patience, like a snake gradually throwing out its old decomposed scales  to come out with a new coat of skin, the the real man."

Yes anger knows now limits.

But fortunately for Hanuman the Ashoka Vanika was not gutted and he could meet Sita once again before he left Lanka.
