Maybe someone has wondered. It's actually 'jig rten mig, 'jig rten means this world, mig means eyes, so it's eyes of the world, translator, or in Sanskrit lotsawa. In Tibet it was considered quite an achievement for someone to learn another language, such as Sanskrit, and translate the spiritual meaning back to the culture. Such people were considered the 'eyes of the world', so others could also see truths via these 'jig rten mig. So that might be another inspiration why we in the West need more and more 'jig rten mig, not that there are many wonderful translators already working and benefiting us.
