I made this before but for the people that didn't see it here it is.
If somebody used earth style and flying rocks came at someone who can absorb ninjutsu it wouldn't work. Because those rocks aren't made up of chakra. If somebody uses a technique that uses chakra from the body it can be absorbed. Naruto's rasengan was able to damage Juubtio on account that his rasengan was made from nature energy. that's why you hear sage art: giant rasengan. It wasn't made up of chakra from the body. For example how did Madara get hit with that wind from Temari and why didn't he just absorb it? It's because her fan created that gust of air natually but waving the fan. if she were to blow a gust of wind from her mouth on the other hand it would get absorbed. Naruto's rasenshiruken was absorbed because he had his wind chakra added to it. There's a difference between wind and wind chakra.
