The Relevance of Kabir is also book about relationships. It takes many examples from real life relationships to point out the misery causing habits of mind. Here is an excerpt.
“He [Kabir] does not say that spiritual seekers or ascetics will comprehend his meaning, but notes that lovers will. Our poet wants us to have the experience of being in love as a step toward greater liberation. Lovers mistake the dissolving of the ego in orgasm to be only part of orgasm when it results from arresting habits of mind. If we can’t let go of our self, orgasm becomes difficult. In the ecstasy of love, the mental specter of our self becomes unsustainable. We live without a story for a few moments. If we need others to see beyond our ideas of ourselves, then possessiveness haunts us. We become a burden to others and limit our choices by reducing people into nothing more than a means. When we use people, we probably destroy or limit our affections in the process. Emancipate others from being just a prop in a cerebral autobiography.”
