アヤワスカを6回飲んだ植物学者「性・死・快楽」が一つに溶けた世界｜山下知道 × シャーマンriyo

Scientific Concepts / Discoveries / Nature Phenomena

Psychedelic plant experience (Ayahuasca / “Wakamasu” / “Peruvian Dead Man”)

• Ayahuasca intake frequency & timing

  • The botanist describes drinking it six times.
  • Effects are reported as following a relatively fixed schedule, with onset around ~30–40 minutes.

• Vision / psychological phenomenology

  • Recurrent visions include:
    • Seeing past self and “time-like” extensions of past/future “dream” space.
    • A “funeral”/death-symbol experience plus prolonged “die die” chanting, described as difficult/hard/dark.
    • Encounters with a dark inner world and an ego-related collapse, including:
      • “No ego,” reduced desires, and heightened clarity/direct perception.

• Dark/light integration

  • The experience is framed as involving an internal dark side (trauma, sadness) alongside light.
  • Emphasis that shamans are also human, carrying scars from childhood.

Botany & ecology framing

• Flowers and plant perception

  • The speaker highlights that the psychedelic/medicinal plant has flowers, noting that many people don’t know this (presented as a botanist’s perspective).

• Soil, decomposition, nutrient cycling

  • A vision emphasizes:
    • Soil as required for plant growth
    • Decomposition: leaves → insects/cockroaches → further breakdown → dissolution into water.

• Plant–microbe “energy exchange”

  • The account claims a perceptual understanding of plants exchanging energy with microorganisms/bacteria.
  • In the visionary account, this occurs rapidly via light.

• Time dilation / perception of epochs

  • The speaker reports feeling ~1000 years while real time is much shorter (about 56 minutes).

“Oneness” as non-uniform blending (nature-inspired)

• Gradient over binary

  • Nature is depicted as gradational (marbling/continuous color transitions) rather than black-and-white.
  • Mental liberation is framed as embracing “elements in between.”

• Individuality-preserving unity

  • “Oneness” is described as:
    • Blending together while keeping distinct individuality
  • Analogized with different colors combining without erasing uniqueness.
  • The speaker critiques “forced spirituality” or a “cult of oneness.”

---

Ceremonial tantric / sexuality and womb-love framing

• Ceremonial tantra

  • Monthly ceremonial tantric practice is described as connection with self and others.
  • Orgasm/sexuality is reinterpreted as spiritual/relational rather than adult-video–associated.

• Shrine etiquette and “mother womb” symbolism

  • Shrine worship is interpreted as respect toward origins (“mother womb”).

• Cellular-level memory

  • The account claims memories tied to womb/birth can be restored, presented as “cellular-level memory.”

---

Birth trauma and modern vs traditional birthing

• Birth trauma

  • “Birth trauma” is described as pain/difficulty at the moment of birth.

• Hospital vs community/midwife environments

  • The claim is that moving births to hospitals (Western medicine) replaced more natural, family/community support.
  • A loving environment is suggested to reduce trauma and help recovery of suppressed feelings.

---

UFO / aliens and cross-dimensional phenomena (as reported in visions)

• UF/aliens during ceremonies

  • UFO-like phenomena are reported as typically appearing during the ceremony.
  • Visual forms are described (including a fairy-like entity) and “dimensions” intersecting.

• “Transparent activities”

  • Mentions a kind of practice/activities suggesting altered perception and “transparency” themes.

---

Nature communication / interconnection

• Communication beyond human language

  • After the ceremony, the speaker reports a feeling of communication with nature (birds, wind) beyond words.

• Connectivity and loneliness

  • Suggests modern people—especially in Japan—may experience greater loneliness, which reduces awareness of connection.

Method / Process Outlined (as described by participants)

How the ceremony is prepared & conducted (as inferred from dialogue)

• Ingestion timing

  • Take ayahuasca (“Wakamasu”) and monitor timing:
    • Onset/transition around 30–40 minutes

• Diet / pre-ceremony food

  • “Incorporate food” to make reactions easier to manage when intersecting with other dimensions.
  • Eliminate other foods (unspecified) to facilitate easier response.

• Ceremonial “formula” may differ by shaman

  • Different shaman preparations lead to:
    • Slightly different “formulas”
    • Different taste/effects

---

“Interpreting” experiences (shamanic perspective)

• Prioritize

  • Transmission across generations and cultural meaning
  • Connection with ancestors

• De-emphasize

  • Whether the experience is objectively “scientifically correct”
  • Treat it as spiritually important within its cultural context
