That is the prinnciple of the jutsu.You now know it.Train with a clone to get the hang of it fast.As the weak lightning jutsu is released, I form a short sequence of hand seals and raise my arms, I then face them toward the oncoming jutsu, as the jutsu makes contact with me, I absorb the lightning chakra from it and reserve the lightning for my own lightning technique.
Yeah that is one of the ways.So the secret behind the jutsu is molding earth chakra.Backside is you have to keep your contact with the earth.You put your hands on the ground and start to mold earth chakra until the golem form you want is created.How many closed eyes you have depends how many eyes the golem will have-1 or 2.If you make two golems each golem will ahve one eye.The main think is to keep your hands on the ground,keeping the focus on the golem and from there let your imagination wild.You can regenirate limbs create extra such but 2 eyes is the max and yours must be close(think of how Gaara uses his Sand Eye).Keep your eye/eyes closed, otherwise either the golem will disappear or the eyes on the golem will close.I could use the avatar to fight at close range for me while I am perhaps hiding somewhere.
