- Assumptions about Others : Negative self-perceptions and misconceptions about happiness are common assumptions people hold, which can impact personal well-being and relationships.
- Assumptions and Morality : The moral judgment of actions, such as corruption or pollution, is often based on assumptions shaped by personal benefit, illustrating that assumptions influence perceptions of good and bad.
- Assumptions in Science : The trust in scientific studies can be misplaced given that a significant number are later contradicted or invalidated, highlighting the importance of skepticism.
- Assumptions in Religion : Core beliefs such as the historical existence of religious figures are often unexamined assumptions that can be deeply unsettling if questioned.
- Unexamined Daily Assumptions : Daily actions, like eating, are based on numerous uninvestigated assumptions related to the safety and quality of the food we consume.
- Meta-Assumptions and Worldview : Acknowledging and scrutinizing meta-assumptions, such as the assumption of objective biological facts or inalienable rights, can profoundly affect one's worldview and understanding of reality.
- Existential and Philosophical Assumptions : Assumptions about existence, consciousness, and the permanence of objects impact our understanding of our place in the world and the nature of reality itself.

He further questions the assumption that science is the best epistemological method.
- Scientific Dogmatism and Rationality : Leo discusses assumptions about the self-correcting nature of science, its coverage of all that is real and true, and the equation of scientific functionality with truth. He also contests the belief in the logical and rational nature of all truth.
- Misconceptions about Science and Mysticism : He explores the contrast between science and mysticism, noting the assumption that science will eventually demystify all reality and the belief that reality is finite rather than mystically infinite.
- Challenging the Foundations of Reality : Leo suggests assumptions about consciousness, the scientific method, the mathematical reality, cause and effect, and the simulation theory should be questioned. He also addresses the validity of miracles and the reasoning behind reductionism in science.
- Misplaced Faith in Gurus and Enlightened Masters : He warns of assumptions in spirituality, such as the inability for enlightened masters to be fallible or wrong, the universal efficacy of meditation, and the dangers of blindly believing in gurus or mystical teachings.
- Exploring the Nature of Consciousness : Leo challenges the assumptions surrounding the objectivity of science and mathematics, the dichotomy of mind and body, and the highest levels of consciousness and awakening.

- Impact of Challenging Societal Assumptions : Addressing the resistance faced when questioning widespread societal beliefs, Leo underscores the importance of persistently examining common assumptions to cultivate a stronger sense of reality and encourage personal and collective growth.
- The Nine-Dot Problem and Assumptions : The nine-dot problem serves as a powerful metaphor illustrating how assumptions can limit thinking. It shows that we often operate under implicit assumptions — in this case, that lines must be drawn within the confines of the dots — which restrict our problem-solving capabilities. Leo Gura uses the nine-dot problem to exemplify how challenging one's own internal limitations can lead to paradigm shifts, revealing a more expansive approach to solving life's challenges.
- Overturning Implicit Assumptions : Changing deeply ingrained, implicit assumptions can be shocking and lead to significant paradigm shifts or recontextualization. Leo discusses episodes from his series that touch on this concept, explaining how an individual's understanding of reality can radically shift by questioning self-imposed limits.
- Finite Reality as an Assumption : Leo criticizes the materialist assumption that reality is an objective, material system. He introduces the idea that reality might be an infinite mind, and when it imagines certain limits, they become realities. He suggests that spiritual and personal growth work entails removing perceived objective limits, such as those suggested by physics, by changing one's perspective.
- Questioning Fundamental Assumptions : Leo stresses that advanced spiritual truths are inaccessible to most because they haven't questioned fundamental assumptions deeply enough. He challenges the assumption of death's inevitability, suggesting that people cannot fathom the idea of not dying because they accept the construct of death without deep questioning.
- The Work of Questioning Deeply : Leo clarifies that his work isn't about indoctrination into belief systems but focuses on profound questioning of assumptions. Going beyond ordinary thinking leads to epiphanies inaccessible to the "ordinary mind," which may dismiss such insights as irrational or flawed without understanding the significance of assumptions.
- Exercise in Questioning Assumptions : Leo suggests listing all major life assumptions that turned out to be false and reflecting on their impact. This exercise can reveal why certain assumptions were made—often out of a need or desire for them to be true, which can be emotionally protective.
- Consequences of Challenging Collective Assumptions : Questioning everything in your life can have profound effects but will also draw resistance. Assumptions are vital for the survival of self-constructs within individuals and institutions like businesses or churches. They enable group think and collective egos, and challenging them threatens the groups' survival.
- The Power and Pitfalls of Collective Fictions : Leo discusses the power and drawbacks of collective fictions, noting that they can take on the appearance of reality if embraced by a significant number of people. Despite their utility, defending these fictions may result in conflict or violence, as they become integral to individual and collective survival.
- Valuing the Challenging of Assumptions : He argues that despite potential resistance, deeply questioning assumptions is critical and can lead to broader insights. This process is the core of good epistemology and deep contemplation, which requires open-mindedness and persistence.
- Investment in Unearthing Assumptions : Leo concludes by encouraging the continuous effort to question assumptions, touting it as a valuable investment. This practice of good epistemology may require substantial time and dedication, which, while initially may not seem rewarding, ultimately pays significant dividends through deep insights into the true nature of reality.
