Did Steiner write on that? The interplay between the will forces (intending, aspiring, applying, pursuing) and the more receptive states. I find it still quite trendy in spiritual jargon (New Age primarily) to speak of "surrender" and the need for surrender and fair enough but what we are surrendering to? The "flow" could well be the status quo and the programmed societal narratives of control often times. The path of least resistance is not necessarily the higher path, the moral path.
On that subject, another philosophical question that has always had a grip on me: free will or destiny? It could be paraphrased as old karma or new karma? We create new karma every day and yet there are fated events and consequences all derived from past karma. I'll pause here as too much to ponder 😜 Any reflections welcome!
