Playing a bit of devil's advocate here: why the need for a teacher?
Buddha: "No teacher have I"
Jesus: "Know thyself"
I'm not convinced there is a "Buddhist way", but rather ways. I mean, Vipasana is almost entirely technique oriented, apparently following the historical Buddha's extant teaching to the letter. Tibetans do a boatload of visualization, while Zen tends to emphasize open eyed sitting and posture without any focal point.
Same deal in Christianity, Islam, etc., many ways.
And yet, mystics like Ramana Maharshi, Jiddu Krishnamurti, Eckhart Tolle, etc. all say, dispense with practice and teachers, these are extraneous to the fundamental matter. For Tolle it was rock bottom chronic depression; for Maharshi it was some kind of death experience, and for Krishnamurti it was talking a lot (heh, heh, kidding, he was apparently born without the sense of "I").
