Oh undoubtedly, I personally follow advaita teachers like Spira and Adyashanti because they just tell people to look for themselves, to take a hard look at the current beliefs we have and find out why we believe. Is it because of something we've found in our experience?

Most of these teachings are extremely repetitive because there's only so many ways to say the same thing, they're still great reminders, so I use them before meditation practices.

I've come across my fair share of "spiritual teachers" pushing their own agendas
