SOLVED. looking for the tittle of a spirituality book name

[Ares]

i am looking for the title of 1 book, paperback, -i guess there is no ebok version-, about spiritual teachers, like the

"teachers of one" by Paula Marvelly or "the awakening west" the Lumiere's, in content, but

the cover is blue, with some faces on it, and 1 of the persons interviewed-revised was Andrew Cohen (it's not the book by John David),

any help please?

found it: Book of Enlightened Masters: Western Teachers in Eastern Traditions by Andrew Rawlinson (it is not a blue cover, but purple) lol
