of the Guru of-the-Month Club, and the motto is: "If you don't believe in yourself, find someone who agrees with you and follow them." Among the texts of the pali canon I think I recall it saying find one teacher and stick with them don't shop around too much. But how much is too much? and in this day and age there are so many teachings available - I do Know for Certain that the Buddha said the Dhamma is found in all sorts of places and on many many paths - if it brings true happiness it is in keeping with the Dhamma, but no matter where you find it or who said it we must check it out for ourselves and if it works, use it, if it doesn't, then set it aside.
We would be foolish to neglect the marvelous teachers and teachings available to us, Sensei teaches us to develop discernment and critical thinking to identify what is helpful and what is not.
