The core of tantric Tibetan traditions has historically described the ability of meditators to achieve a “forceful” induction of “pulsations of energies” inside the body through practices such as those perceived in Tummo-Yoga meditation. Classical text describing these reveals the “drawing [of] the vital energies” are “brought under control” by “changing energy flows” inside the body. Sensations are described to produce an “all-pervading energy”  leading to “ecstatic” sensations conveying precisely modern practices associated with the induction of the “Vibrational State” (VS). Such powerful practices are often conducive to Out-of-Body Experiences (OBEs) as portrayed in the Northern wall mural at the Lukhang Temple in Lhasa, Tibet, from the 17th century depicting both Tummo-yoga (inner fire) and Phowa (transference of consciousness or OBE) associated with such practices. The state is suggestive of an overall activation of the human biofield.

Our neurophysiological research into the induction of the VS in long-term practitioners (see video below) indicates such training enhances high Gamma waves - brain waves associated with insight and high brain internetwork connectivity. More so, our current research suggests the state has similar EEG characteristics and phenomenology than reported in some N,N-Dimethyltryptamine (DMT) experiences.
