Lightning basically consists of discharge of electricity between 2 points 
when the potential differance between them is so great that it is able to 
conduct through the air too.

As air is a non conducting medium (for practical purposes) the lightning 
discharge is of a very high voltage. However the currents generated is 
extremely small.

Thus despite the high voltage, which the man is subjected to, virtually no 
current passes through him. So the amount of electricity passing (ie: 
charge) is negligible.

Thus the man has a chance of survival even after a direct lightning strike.

I'd be glad to help you out if you have any further queries regarding 


P.S.:(230V can kill a man, but when you accidentaly touch the socket, you 
get a rude shock, but dont die )
