We propose that the culminating dimension of inner balance is spiritual intelligence and maturation—a quality of well-being that carries one through all the vicissitudes of life and death. It derives from knowing ourselves and our relation to reality as it is. This leads to liberation through insight. Such insight, or spiritual intelligence, is sustainable only in dependence upon the prior cultivation of psychological well-being, stemming from the cultivation of the preceding modes of balance. It also builds upon both the social and environmental flourishing that derive from the development of ethical intelligence.
The cultivation of spiritual intelligence, which makes spiritual balance possible, includes an intentional and deliberate exploration of the innermost depths of who we are and how we relate to the rest of reality. It includes seeking time-tested teachings and qualified teachers who inspire one to keep striving for genuine happiness, regardless of discouraging obstacles. It integrates meditation practices for exploring the actual nature of one’s own identity, so that one might gradually discover the true source of all well-being and fundamental healing.
Cultivating spiritual balance includes ongoing communication with teachers and fellow practitioners, consistently checking oneself and one’s practice in relationship to a supportive community, and emulating established examples from the past. It focuses on truth.
As so many sages of the past have emphasized, the highest joy—the highest eudaimonia, the summit, the pinnacle—is a truth-given joy. This comes from discovering the innermost source of well-being and wisdom. That is the highest bliss. It is in accord with the most ancient aphorism of western civilization, the Delphic Oracle, “Know thyself!”
