Sanskrit is the language of the ancient texts, the unbiased definitions of Yoga practice. The true teaching of the true Yoga teachers. It is an amazingly beautiful language, constructed thousands of years ago to preserve the wisdom from the first known researchers on mind, conciuosness and the self. Pronunciation, alphabet, construction of words and sentences. All components are perfectly refined to prevent transmission errors and make sure we can always validate our opinions about Yoga by studying the original meaning of the sacred texts. Without proper pronunciation the meaning of words gets distorted and the carefully constructed combinations of rhythm and sound break down.
Learning correct pronunciation of Sanskrit and language in general requires mindfulness and therefore is a Yoga practice by definition. Moreover through that process you contribute to preserving the ancient wisdom of the original Yoga, untaintend by the processes that have transformed mainstream „Yoga“ into an empty commercialized facade.
