idk very well what you mean with meaningful questions, but it reminds me of my own search for something different from the conventional RC, which just seemed full of contrivance and short sightdness and keep me on this duality of waking and sleeping. And in that search, i am learning that some aspects of our minds are always on whether awake or asleep, and that became a main theme of reflection and mindfulness, because i could not only derive the benefits of LDing but actually the taste of incipient nonduality, which keeps improving. That's just a very special and definitive version of ADA, a very relaxed and meaningful one.

So i would say you need a minimum of applied mindfulness, that is, directed to some critical aspect, or you could say mindfulness coupled with insight. The way i do it, in short, is to mindfully notice my own basic cognizance. I have some threads about it.
