I understand that Reiki is healing with energy. There are classes, attunements with special symbols performed by the Reiki master, and there are certain hand positions for healing certain parts.

My question is like this. Could it still be effective healing without the attunements and symbols? Like if i learned it via videos and reading, would that still be pretty effective? i feel like it wouldn't be real Reiki without those which is my reasoning for the title. But it i were to channel energy In the same way, use the proper hand positions and such, could i still heal someone or myself?
