Ninjas train under great Sensei, that's why they have great abilities. Ninjutsu enhanced their strength and the beliefs of Nature. But Mostly because Ninjas train hard. By great abilities what do you mean ? Disappearing? flying ? killing 20 men ? If the truth be known and if you search for books on Japanese history there are no real documented cases of any of these things happening - the ninja is a confusing term - a ninja - shinbi whatever you want to call him could have been anything from a spy to a poisoner, they were just covert mercinaries that would murder or steal or watch who ever you had a grudge with.
