I finally caved and purchased a couple of books on Bhakti yoga. One was a small tract by Swami Vivekananda. The other was The Yoga of Spiritual Devotion, which is a translation of the Narada Bhakti Sutras, with commentary by Prem Prakash.
The former was a slight disappointment for no real rational reason other than its dry, cold tone, but the latter has broken me wide open. I’m not sure how I should proceed, except to surrender.
So surrender I shall.
