4. What happens when you sleep?

Hey! I'd love to hear your thoughts, send me a voice note.The waking, dreaming, and deep sleep states and the fourth that underlies them allEvery night, without exception, you disappear completely and come back. What actually happens in between?This episode takes the most ordinary thing you do every single day and turns it into one of the most precise philosophical investigations available to a human being. Drawing on the Mandukya Upanishad - the shortest of the principal Upanishads at just twelve verses, and one of the most rigorously argued texts in the entire Vedantic tradition - Nicky walks through the teaching of Avastha Traya: the investigation of waking, dreaming, and deep sleep, and what remains present through all three.You'll be guided through each state in turn - the world you take to be obviously real, the dream world your own mind constructs and then completely believes, and the deep sleep state where both dissolve entirely and yet something is still there to report on it. From there, the episode introduces turiya, not a fourth state, but the awareness underlying all three, present and unchanged through everything. Along the way: an honest engagement with the sceptic's strongest objections, Gaudapada's radical teaching of ajata vada, and the elegant mapping of the whole teaching onto the sound of AUM.This episode is intimate rather than academic in tone - less a lecture, more an invitation to look at something you already have direct access to, tonight, in your own bed.In this episode:The three states — waking (jagrat), dreaming (svapna), and deep sleep (sushupti)Why the Mandukya Upanishad uses your own nightly experience as its method, not abstract argumentGaudapada's Karika and Shankara's commentary - the layered philosophical foundationWhat deep sleep actually reveals about the nature of the selfTuriya - the fourth, and why it isn't a state at allThe sceptic's case, addressed directly and without dismissalGaudapada's Ajata Vada - the doctrine of non-originationHow AUM maps onto the entire teaching, sound by soundWhy this matters: suffering, the fear of death, and the nature of the present momentReferences and further reading:The Mandukya Upanishad - trans.
