The last century has seen the emergence of a new generation of co-creator pioneers—not as mythic prophets or secluded mystics, but as practitioners, healers, scientists, and explorers who document their experiences in the fourth-level reality with clarity and precision. These individuals are mapping the unseen realms not through religious dogma, but through direct perception, disciplined inner practice, and experiential validation. They are midwives of modern spiritual science, bridging consciousness and cosmology.
Over the past 50–100 years, many individuals have begun actively co-creating with divine realms, not as prophets or saints, but as everyday pioneers—healers, researchers, therapists, and consciousness explorers. These individuals have contributed to the emerging science of the fourth-level reality, offering frameworks, experiential accounts, and methodologies for engaging higher dimensions with integrity. What unites them is a shared commitment to experiential mapping of non-physical realities, developing clairvoyant or expanded perception, emphasising healing, integration, and planetary service and anchoring multidimensional knowledge into practical application.
Modern
Co-Creators
The Theosophy Lineage
Founded in the late 19th century by Helena Petrovna Blavatsky, and further developed by Annie Besant, C.W. Leadbeater, and later Alice Bailey, Theosophy introduced a multi-plane model of existence that deeply parallels the fourth-level framework. These thinkers emphasised direct access to the subtle planes—astral, mental, and causal—through the refinement of consciousness. Theosophy encourages co-creation through systematic clairvoyance, understanding the seven planes of existence, engaging with Masters of Wisdom and the Spiritual Hierarchy, and planetary service via meditation, invocation, and esoteric healing. Their works laid the foundational vocabulary for understanding the fourth level as part of a larger cosmic structure, influencing spiritual science, esoteric psychology, and the language of lightworkers today.

Robert Monroe
A pioneer in out-of-body exploration, Bob Monroe founded The Monroe Institute and documented his journeys into the astral and beyond in books such as Journeys Out of the Body. Through direct experience, he described subtle environments, beings, and learning zones within the fourth-level reality, and developed audio technologies (e.g., Hemi-Sync) to assist others in navigating altered states. Contributions include astral travel as a learnable skill, mapping levels of consciousness beyond the body, offering neutral, non-dogmatic language for multidimensional reality and emphasising integrity, curiosity, and service in exploration.
Barbara Anne Brennan
A former NASA physicist turned clairvoyant healer, Barbara Ann Brennan is one of the most influential figures to bridge science and spiritual energy dynamics. Her groundbreaking books, Hands of Light and Light Emerging, have introduced millions to the multi-dimensional structure of the human energy field, and her healing work offers some of the most detailed maps of the fourth-level reality ever published in contemporary spiritual science. Brennan’s contributions extend beyond therapeutic insight. In Emerging Light, her final and most intimate book, she documents personal journeys into the fourth dimension, describing with clinical precision and spiritual sensitivity how she would expand her energy field, leave her physical body, and traverse subtle dimensions to locate and heal unresolved energies—sometimes from other lifetimes, sometimes from family lineages. Her work highlights the transformative power of the fourth level. She describes it as an emotionally responsive, luminous space where symbolic perception replaces linear thinking. She travelled within the astral planes to visit healing temples, encounter spirit guides, and retrieve fragmented parts of her consciousness—practices that align with ancient initiatory traditions but articulated in modern psychological terms. Brennan also interacted with her clients at the fourth level, facilitating healing at the energetic root before changes became visible in the physical body.
Perhaps most remarkably, Brennan presents a foundational model for the science of the fourth dimension in her articulation of the “39 Principles of the Physics of the Fourth Dimension”. These principles echo and inform the emerging science we are now constructing. They include:
-
The influence of vibrational frequency and resonance in shaping perception
-
The role of intent, emotional coherence, and imagery in fourth-dimensional navigation
-
Laws of energetic causality, showing how emotional blocks manifest as disease if unhealed
-
The ability of energy-conscious practitioners to create localised energetic fields for healing, protection, or awakening—early evidence of spiritual technology.
Her work is pioneering in that it provides repeatable methods for accessing the fourth level, validates clairvoyant perception within a disciplined, structured framework, bridges biofield research, chakra anatomy, and psychospiritual development, and acts as a scientific and mystical manual for those walking the path of the divine human. Barbara Ann Brennan is not only a healer—she is one of the foremost scientists of subtle energy, and her writings are cornerstones in any attempt to build a formal science of the fourth-level reality.
A respected Theosophist and clairvoyant explorer, Kurt Leland has offered one of the most comprehensive experiential maps of the astral and mental planes in modern times. Through deep meditative journeys and careful phenomenological tracking, Leland describes healing temples, schools, libraries, guides, and the fluid logic of non-physical space. His book Otherwhere is a fourth-level travelogue written with clarity, humour, and psychological insight. Contributions include fourth level as an educational and healing dimension, psychic hygiene and discernment in subtle spaces, bridging mystical traditions with personal experience and respect for the astral symbolic logic and emotional responsiveness.

Barbara Marx Hubbard
A visionary futurist and author of Conscious Evolution, Barbara Marx Hubbard taught that humanity is in the midst of a planetary shift toward divine co-creation. She reframed mystical transformation as an evolutionary imperative, advocating for group coherence, conscious birthing of new realities, and the emergence of the Universal Human—a direct parallel to the Divine Human archetype. Contributions include framing co-creation as a collective spiritual emergence, linking planetary service with divine purpose, initiating social and spiritual movements that reflect fourth-level principles and bridging science, mysticism, and social change.
