I had never mediated before...A few instances of 20 minutes that were guided, but never 'for real'. I went in not really knowing what I would be asked to do or how it worked. For me, that worked wonderfully.

I generally tend to fail magnificently at first and then flourish very quickly after making all the rookie mistakes all at once.

If you have questions, don't be afraid to use the question sessions to speak to your teacher. If it seems like the instructions are too simple, you might be overthinking it. It's all about letting go after all.
