Hindu japa malas and Buddhist prayer beads hold 108 beads, while the Sufi misbaha holds 99 for the names of God, and the episode uses them to show how separate cultures built physical anchors for attention. A Delphi study of experts identified logic relaxation, setting aside the evaluating mind, as a core element of meditation. Practices fall into focused methods and open monitoring, often taught in sequence, as with Buddhist samatha followed by vipassana. Posture aims to balance alertness and relaxation, whether in lotus, on a zafu cushion, in a chair, kneeling in seiza, or walking in kinhin. Transcendental Meditation prescribes 20 minutes twice a day, while Richard Davidson points to benefits from eight minutes a day.

The earliest clear written references appear in the middle Upanishads and the Mahabharata, and Patanjali, around 400 CE, placed meditation within an eight-limb system starting with ethical rules. Buddhism reached China by the second century CE, merged with Taoist breath practice described in the Guanzi, and became Zen, which spread to Japan. Jewish Kabbalah, Christian hesychasm on Mount Athos, Guigo II's Lectio Divina and Sufi dhikr developed their own methods. The 1893 World Parliament of Religions in Chicago introduced Swami Vivekananda and Anagarika Dharmapala to Americans, and Herbert Benson's 1975 The Relaxation Response secularized the practice. The episode closes on documented adverse effects, from dissociation to hallucinations.

• Zen monks sometimes requested a strike from the keisaku, the encouragement stick, to break mental fog.
• Rhythmic chanting slows breathing to about five or six breaths a minute, which the episode links to the vagus nerve.
• Sufis contrast dhikr, remembrance, with fikr, ordinary thinking.
• Guigo II's ladder moves from reading to pondering to prayer to contemplation.
• The U.S. National Center for Complementary and Integrative Health has cautioned against overly optimistic readings of the research.
