This invitation/revelation/transformation—this unfolding of the soul—is what we call the adventure of Being: the open-ended journey in our Spacecruiser Inquiry to the farthest reaches of space. However, to take part in this adventure, we must comprehend more fully and exactly what knowledge is, and how it is relevant to our inquiry. – Spacecruiser Inquiry: True Guidance for the Inner Journey, ch. 5
While mind is a necessary instrument for discerning and synthesis, the heart lights the way to uncharted territory and enables one to feel and know with intimate immediacy. The two work as one to charter the inner realms, much like the mariner’s astrolabe. The heart provides the sense of direction toward the innermost reality; the mind contributes its gift through its capacity for discrimination and understanding in the wake of experience. – Karen Johnson, The Jeweled Path: The Biography of the Diamond Approach to Inner Realization, Ch. 3
