Living in Flow as Psychological Baseline: Reframing Ego, Self, and the Default Mode within UPC Psychology

Contemporary psychology and neuroscience largely assume that a coherent, bounded ego or narrative self is the cornerstone of mental health. This view is often linked to the Default Mode Network (DMN), whose activity during self-referential thinking and autobiographical processing has led some to describe it as a core neural correlate of the narrative self. In parallel, flow states, meditation, and psychedelic ego dissolution demonstrate that human experience can function optimally when self-referential activity is reduced, reorganized, or temporarily suspended. In this paper, a consciousness-oriented psychological framework—Unified Play of Consciousness (UPC) psychology was developed that treats everyday flow states (flow in ordinary life contexts), rather than egoic self-occupation, as the more natural and healthy baseline of human functioning. Within this view, the "self that actually exists" is not a reified inner entity, but a limitless configurational potential that can be shaped into resonant patterns of thought, feeling, and action. Structural orientation is provided not by defending a rigid identity, but by aligning with values, wishes, and goals that define a personally meaningful trajectory. The proposal is situated in relation to empirical work on the DMN, flow, meditation, and psychedelics, and theoretical work on self-models, Acceptance and Commitment Therapy (ACT), Self-Determination Theory (SDT), predictive processing, and the interplay between the default mode and task-positive networks. Articulates core propositions of UPC psychology. Anticipates key criticisms (e.g., "ego is necessary," "flow cannot be a baseline," "this is metaphysical or unfalsifiable") and offers rebuttals. Outlines testable predictions using resonance–dissonance indices—such as the Resonance Quotient (RQ) or Polarity Accessibility Score (PAS) derived from the UPC Metrics framework—everyday flow state measures, and neuroimaging endpoints. Short Resonance Optimization Practices (ROPs) are proposed as practical tools for stabilizing resonant everyday flow-state configurations. While the broader UPC framework views all experience as unfolding within awareness, this paper brackets detailed metaphysical claims and focuses on empirically tractable questions: Can an everyday flow states-centered, resonance-based model of self-regulation be operationalized, measured, and empirically compared with ego-centered models of psychological health?
