PATANJALI: Discoverer, Differentiator and Disruptor’

Patanjali and neuroscientific research on meditation

The definition of meditation (or yoga) by Patanjali as " restriction (or stilling) of the fluctuations of the mind " (cf, Woods, 1927/2003, p. xxx, 8) may be an appropriate starting point for research on meditation using fMRI. An operational definition of the neural substrate of meditation which is adequate to Patanjalis definition, may be developed on the basis of a non-reductionistic understa...

Clinical hypnosis and Patanjali yoga sutras

The trance states in yoga and hypnosis are associated with similar phenomena like relaxation, disinclination to talk, unreality, misrepresentation, alterations in perception, increased concentration, suspension of normal reality testing, and the temporary nature of the phenomena.

Initially schooled in Scotland, Fleming eventually moved to London with three brothers and a sister, and completed his youth education at the Regent Street Polytechnic.

Rapid-convergent nonlinear differentiator

A hybrid nonlinear differentiator being fit for rapid convergence is presented, which is based on singular perturbation technique and consists of linear and nonlinear parts. This differentiator is simple and can converge rapidly at all times, and no chattering phenomena happen. The theoretical results are confirmed by computer simulations and an experiment.
