The Ra Material is the most powerful literature in existence.

[Poet]

This question reminds me at this quote of Ra I read yesterday (hope it wasn't a rhetorical question because I didn't read the whole thread).

15.22 Questioner: You also said that you offered the Law of One, which is the balancing of love/light and light/love. Is there any difference between love/light and light/love?

Ra: I am Ra. This will be the final question of this time/space. There is the same difference between love/light and light/love as there is between teach/learning and learn/teaching. Love/light is the enabler, the power, the energy giver. Light/love is the manifestation which occurs when light has been impressed with love.

I would say a good teacher always tries to get into a conversation with his pupils. He is not afraid to give up his standpoint in a discussion, because he doesn't feel that he has to defend his own position. This makes it easy for him to loose his opinion/position and to learn from his pupils. The main goal such a teacher has is "finding the truth" or at least "getting closer to the truth" in interaction with others (which is a service).

For me, teaching and learning are just from the outside two different activities. You could maybe argue that the teacher also possesses some kind of authority but this is not always the case in my opinion. If you go to the core, both words describe the same activity which is "finding the truth" in interaction with others.
