Inquiry. Plain and straight. No abrupt magical words dropping from the heavens. No convolutions of the intellect. No conclusions asserted just because someone said something. Just simple inquiry, where you are true to yourself. And only then, you will see, that Devotion is also possible. Because, Math and Melody are not divergent. While inquiry starts with articulate questions, devotion starts in a state of inarticulate question (you see, it takes two question marks to make a heart!). Either is possible only when Thought is startled. And neither is possible when one is dead sure in beliefs.
