Anger ends in shame

क्रोधो हि शत्रुः प्रथमो नराणाम्
देहस्थितो देहविनाशनाय ।
यथा स्थितः काष्ठगतो हि वह्निः
स एव वह्निः दहते शरीरम् ॥

Anger is foremost enemy of humankind, which inherently resides within oneself only to destroy him, just like fire which is enkindled by a piece of wood ends up burning the piece.

Whatever is begun in anger, ends in shame.
Anger is just one letter short of danger!
