Dalai Lama, on choosing a teacher

I was rereading my notes today, from the Dalai Lama's 1996 Kalachakra Initiation in Sydney, Australia. I'll paraphrase for now, and replace with the precise quotes when I bring my book in.

Seek a teacher who embodies what they teach (practices what they preach).

If what a teacher is saying does not follow reasonably and logically, that person is not a holder of the truth.

If what a teacher is saying is inconsistent, that teacher is working at the interpreted level.

If what a teacher is saying is true and valuable, it is a good teaching.

We say, "That is a good teaching, that Buddha Shakyamuni gave." We do not say, "That must be a good teaching, because it was Buddha Shakhamuni who said it."

We can only know the quality of a teacher, by the quality of their teaching.
