Acharya Prashant explains a famous verse from the Kena Upanishad, which describes the ultimate reality as the 'ear of the ear' and the 'eye of the eye.' He clarifies that physical organs like the ears and eyes do not possess independent life; rather, they are expressions of a non-physical power behind them. If life resided solely in the physical apparatus, a corpse would still be able to hear and see. He emphasizes that the source of life is intangible and cannot be objectified, yet it is the presence of this source that holds the physical body together and prevents its disintegration. Suffering arises when one mistakenly identifies with the tangible body instead of the intangible essence it represents.
