I found this article, it's talking about the importance of choosing the right teacher
If you do go down this path: don’t trust blindly to what “teachers” / “Gurus” might say, rather trust to those who practice sincerely from the heart over those who lunch / munch upon peoples pocketbooks for purposes of ego and desire. I dont recommend any one teacher, and seriously finding the teacher that is right for you: is your very first test to see if you are worthy and ready to learn . Many teachers are frauds and most seekers fail this first test. Yet belief is a powerful force and few will ever realize this until long after the test.
It's a pretty profound article, its talking about the third eye but I edited that part out of the quote so everyone could appreciate it
