Have a look at this round-up of titles that includes Love between Equals: Relationship as a Spiritual Path.
A committed relationship, as most people see it today, is a partnership of equals who share values and goals, a team united by love and dedicated to each other's growth on every level. This contemporary model for coupledom requires real intention and work, and, more often than not, the traditional archetypes experienced by our parents and grandparents fail us or seem irrelevant. Utilizing the wisdom of her years of personal and professional practice, Young-Eisendrath dismantles our idealized projections about love, while revealing how mindfulness and communication can help us identify and honor the differences with our partners and strengthen our bonds. These practical and time-tested guidelines are rooted in a sound understanding of modern psychology and offer concrete ideas and the necessary tools to reinforce and reinvigorate our deepest relationships.
