Isn't Lama a Teacher?

Lama is just the tibetan word for guru, right? But guru and lama actually doesn't mean teacher. It means one who's deepened in spiritual awareness,. You know, who shares that realization. The first meaning is a gravitos, like a heaviness of spiritual realization. And that's why i have to start, like, i can't stay in the space of being a teacher - i have to always come back to the practice.
