According to the Free Energy Principle (FEP), developed by theoretical neuroscientist Karl Friston and colleagues, much of what the brain does can be understood as minimizing such mismatches—a technical form of 'surprise' defined as the improbability of sensory input given an internal model. The proposal brings perception, action, learning, and decision-making under a single framework.
At the heart of yoga philosophy is the belief that stillness is not simply the absence of movement, but a profound engagement with our inner landscape. Practices such as asana (postures), pranayama (breath control), and meditation serve as gateways to this stillness, allowing us to cultivate awareness amidst chaos.
