just one question, how can we cast genjutsu on the opponent?
I already know the eye contact method and the way an expert can cast a genjutsu just by pointing with his index finger at his opponent (the same way Itachi did during Kazekage retrieval arc)
You mainly need a medium to cast a genjutsu onto your opponent, for example Sharingan genjutsu is cast through the Sharingan looking at your opponent's eyes, a sound genjutsu is cast by a sound instrument, playing a certain melody that's heard by your opponent, if no medium exists, you have to use handseals in order to apply the genjutsu onto your opponent, genjutsu without handseals that's normal is not possible, unless you have a Mangekyou Sharingan, which allows you to cast any genjutsu without handseals as long as you have a clear line of sight between yourself and your opponent.
Now to proceed with the training, i want you to sit in a meditative state, while focusing your chakra into both of your palms, so much that i want to see your palms glow, from the chakra concentration, this will help you in chakra manipulation, which is what genjutsu is all about, it requires tremendous chakra manipulation abilities.
