We recall here what is given in 'Bunch of Thoughts' said by Param Poojaneeya Sri Guruji :
There is a beautiful anecdote narrated in Mahabharata. There was a queen by name Vidula. She sent her son Sanjay to the war-field but the fellow became nervous and terror-stricken. He turned his back to the enemies and galloped to his capital. When Vidula saw her son in that crestfallen state she closed the entrance to the fort and severely chastised him. That conversation between the mother and the son has become famous as Vidula-Sanjay-Samvad, wherein Vidula instructs her son as to how a brave warrior should conduct himself on the battlefield. She then orders him to go back to war and return as a victorious hero. As the story goes, Sanjay sallied forth into the battlefield, displayed exemplary valour and came back to be received by his mother with honour.
Eknathji further says : But it is difficult to determine the dividing line between bravery and cowardice. The circus manager, who can easily handle lions and tigers as cats, is mortally afraid of his wife. He is meek, submissive and tame before her. A man who can successfully fight single-handed with hundred dacoits, loses his courage at the sight of a dead body because dead body implies a ghost and the thought of ghost unnerves him. A man whose potentialities spring up at the sight of a danger is a brave man. He rises to the occasion and at the sight of a tiger, does not run away, but boldly fights with the creature single-handed without any weapon. He is wounded by the tiger and later rescued by the travelers. But he does not know from where the strength arises in him.
That is why, understanding the bravery is essential and it needs to be practiced in day to day life.
