Pancha Kosha: The Five Layers of Human Existence and Holistic Wellbeing Based on the Taittiriya Upanishad, the clinical foundation of the Pancha Kosha Trauma Framework™ at Wellness Space, Ahmedabad Few thousand years back our wise ones knew and understood that we are not just our physical bodies. There so much more to our existence than just the muscles, bones, flesh, blood and organs. Taittriya Upanishad written 3000+ yrs ago mentions the ‘Pancha Kosha’ – 5 Layers of Existence that we all have – which is the basis of the Integrated Yoga Therapy that I have learnt and practice.
