Losing faith in tibetan buddhism I have been practising tibetan buddhism for the past seven years and I am losing faith now and it hurts. I don't know what to do. Can someone advise?
As you can see from people's comments (non-answer) it's hard to answer this question -- not specific enough -- it's phrased as an own-problem without enough detail about its cause or symptoms or the range of acceptable solutions.

Your mentioning "faith" though reminds me of this topic -- What are the differences/similarities in the concept of faith as used in Buddhism and Christianity? -- because it seems to me that Buddhism doesn't have much to to do with "faith" as I understand that word -- maybe it's more to do with "knowledge" (whereas "faith" it sometimes denotes an opposite or absence of knowledge). So almost the opposite of some expressions of Christian doctrine, I think that Buddhism is based on "what you know for yourself to be true" (not only "faith"), which is an attribute of the Dhamma.


  The Dhamma is well declared by the Bhagavā:
  visible here and now, immediate,
  inviting to come and see, effective,
  to be individually ascertained by the wise.


One example is AN 3.66, but the rest of it too, I think that true of all the stages.

Christianity to me only makes sense to the extent that its values are embodied in someone -- if you meet someone who acts like a Christian -- maybe that was an essential part of that religion, starting with the Christ being a person.
Quite possibly some forms of Buddhism (relationship with a teacher, maybe learning from experience) might be like that too.

I'm guessing that "loss of faith" might have one of three causes:


Believing in or having faith in a doctrine -- something supernatural perhaps -- without that doctrine's really making sense to you
Ditto having faith in some practice
Ditto having faith in some person or society


There are any number of possible remedies, I imagine:


Improve your understanding of the doctrine, ask questions perhaps
Improve -- or return to -- your practice, starting with "right view" perhaps


I can't tell you much about Tibetan Buddhism -- which is the only other part of your question. I understand it might involve some personal relationship (with a teacher) therefore possibly vulnerable to the third type of "loss of faith" listed above.

There are dozens of topics on this site which might be related to 'faith' -- see here -- you could browse those titles, to see whether any of those are asking what you're asking and might have an answer.
