Diving in the Inner Ocean

“In simple and easy steps, Dominic invites us to befriend our experience and to gently explore it through to its underlying meanings, coming to depths we have not contemplated and places we have not known in us.”

— from the foreword by A. H. Almaas


Much like the ocean, each of us has inner depths: an entire world beneath the surface of everyday living pulsing with beauty and mystery. This ocean shapes and influences every aspect of our lives: personal growth and development, relationships, interests, and work.

Down in the depths are the very things that we spend our lives searching for on the surface: love, support, effectiveness, belonging, meaning, joy, and freedom. Through the contemplative practice of inquiry taught here, you can begin exploring your inner world just like a diver discovering a reef.

Inquiry combines the depth of meditation with the power of psychological insight. Developed by A. H. Almaas, this simple yet powerful practice is ideal for anyone wanting to explore their inner world and to unlock their potentials, right in the midst of ordinary daily life.

In this book I introduce this powerful tool along with step-by-step exercises to develop your understanding. In time every situation becomes a doorway to deep insight and transformation.

“Dominic’s book elucidating the revolutionary practice of inquiry as practiced in the Diamond Approach path is excellent. It is essential for those new to inquiry and a great enhancement for those already familiar with it.”

— Sandra Maitri, author of The Spiritual Dimension of the Enneagram

“I am delighted that Dominic Liber has written this book. As a teacher of the Enneagram, students often ask me what to do with the knowledge they acquire. And my response is that without practice, such learning cannot take us very far. But here, in Diving in the Inner Ocean, Dominic has provided a beautifully written, lucid, and friendly introduction to what I see as the central practice for working with our personality and for exploring the deeper mysteries of our essential nature—the practice of inquiry. This book guides us step by step into developing the tools and capacities for inquiry, and whether you are an experienced meditator or are new to inner work, the teachings here are a treasure trove of helpful experience and insight. I enthusiastically recommend this book.”

“A brilliant, welcoming gift to the whole world. Dominic Liber lays out a lucid, warm path for becoming competent in an essential skill, diamond inquiry: a contemporary method for uncovering and manifesting our true nature. His work is kind and accompanied in every step with practices, warnings of pitfalls, and pre-forgiveness for any mistakes. Anyone seeking a direct experience of their authentic self will be well served by this compassionate, deeply human, and generous teaching.”

—James Flaherty, MCC, author of Coaching: Evoking Excellence in Others and founder of New Ventures West and Integral Coaching®

“The cosmic ocean of consciousness is such a magnificent vastness—but where to begin? Are you sitting at the shore longing for a way in? Or adrift with only a memory of a rogue wave that grabbed you only to deposit you back on the sand, helpless to find your way back? Do you think the ocean of consciousness is just one thing and miss the riches it holds? With his friendly, encouraging guidance, Dominic illuminates the way to inner exploration with a heart of adventure and the wisdom of a seasoned diver. The pages drip with the presence of the sea as he sharpens our diamond inquiry skill with the innate inner resources that have all but been forgotten. He deftly points us toward the numinous presences of strength, kindness, and steadfastness and sets our curiosity free to explore uncharted waters—all of it—the sparkling, the turbulent, the surface, and the depth. He leaves no shell unturned. Better yet, you will discover all of the magical treasures hidden within each one. Dominic offers an invitation to return to our natural condition as part of that vast sea. You are fluid as an octopus and bright as the bioluminescence that lives at the mysterious depths. Come on in! The conditions are perfect for a dive!”

—Karen Johnson, co-founder of the Diamond Approach and author of The Jeweled Path and co-author of The Power of Divine Eros

“Dominic’s book elucidating the revolutionary practice of inquiry as practiced in the Diamond Approach path is excellent. The process of inquiry allows us to penetrate through our egoic experience and discover the treasures that lie beyond, and is a game-changing innovation in spiritual technology. With clarity and simplicity, he shows us how to navigate our inner life, likening it to learning how to skillfully scuba dive. The analogy of learning to dive into the ocean that he follows throughout is an apt one. He teaches us how to move beneath the surface of our experience and explore what underlies it. As our acclimation to our inner ocean deepens and we become more comfortable, he takes us into the depths of what’s possible for us as human beings to experience. Not only descriptive but filled with exercises for the reader to practice, it is essential for those new to inquiry and a great enhancement for those already familiar with it.”

—Sandra Maitri, author of The Spiritual Dimension of the Enneagram and The Enneagram of Passions and Virtues
