A leader galvanizes action. He spends his solitude in determining and discerning his way through decision processes. It does not mean he makes those decisions on his own, but he does come to a certain peace about what should be done.
When he steps out of his solitude – from the personal dynamic to the social dynamic – he galvanizes action, maximizing the production capacity of everyone around him. If he is a mature leader, he does it in a way that empowers his team. If he is an immature leader he does it in a way that (often) injures his team. Either way he does it. This is true, whether he is Gandhi or Attila the Hun.
