A beginner facing Culadasa I am a complete beginner who was looking for a good Buddhist guide for meditation. I discovered the book "The Mind Illuminated" by Culadasa and I thought I had found the grail: the shape of the guide seemed perfect to me. It is simple and clear, based on the anapanasati, up to the jhanas, step by step.

But I have just discovered the scandals surrounding Culadasa and now I totally doubt the quality of his teaching. I attach great importance to the morality of a teacher of these issues.

Where do I go from here? What do you recommend? Is there another guide as good in its form made by a recognized teacher, without scandals?

Thanks.

Err... not literally...

The point of this quip is that attachment to a teacher is itself something that must be overcome. Even if you are lucky enough to meet a truly enlightened teacher, that teacher's enlightenment is his enlightenment, and you have to find your way to your own.

I'm not familiar with Culadasa or his issues, but a quick google search tells me he indulged in prostitutes and sex outside of marriage. It could be worse — he didn't seem to misuse the student/teacher relationship, as I've seen too many other teachers do — but it still displays some moral turpitude that shouldn't be ignored. Clearly he has a number of miles yet to walk on the path. That is his concern.

Your concern is whether his work advances you on your path. At this point you are not going to be able to see the path all the way to its end; what you want is something that will give you a reliable map for the next few miles, and when you get to the end of that you'll find something that takes you farther. If Culadasa's work feels 'right' to you, follow it for a while. He may have strayed off off his own map into the mire, but that doesn't mean his map is bad, it just means he lost his way. 

Trust me, he spiritual path is littered with teachers who have become object lessons for their own teachings. It's ok to use them as guideposts, so long as you commit yourself to turn right where they turned wrong.
