The Avatar is: "the spiritual entity of the planet manifested in human form. When an Avatar dies, he or she is reincarnated into the next nation in the Avatar Cycle, in the order of the seasons. Legend holds the Avatar must master each bending art in seasonal order as well, starting with their native element. For the Avatar, learning to bend their opposite element can be extremely difficult; the example shown in the series is Aang's inability to stand his ground head-on while Earthbending, his Airbender training having placed emphasis on circling, approaching from new angles and adapting on the fly."
The cartoon is heavily influenced by Buddhist and Hinduism and it's nice to see something that's culturally different. I learned a lot on Buddhism, because the Air Nation was all about it, and everything Aang did reflected that. Every episode conveyed a beautiful inspiring message that a lot of the other cartoons today totally ignore.
Plus all the humour was really funny and refreshing.
See how funny it can be?!?!?! The Air Nomads have such a great sense of humour ^_^
Anyways. I'm having an unnatural obsession right now and I haven't a clue what to do. Aaaaaannnnngggg!!!!!!!!!!!!!!
