"Lambda and Epsilon waves represent two of the lesser-known brainwave states, oscillating at opposite ends of the frequency spectrum. Lambda waves, with frequencies between 100–200 Hz, are associated with advanced meditation practices and profound states of consciousness, as seen in Tibetan monks and individuals like Wim Hof. On the other end, Epsilon waves, with frequencies as low as 0.1–0.5 Hz, are linked to 'suspended animation' and extraordinary consciousness. Despite their differences, these waves exhibit a fascinating interconnection, reflecting the complex dynamics of brain activity during heightened states of awareness."
