This quote suggests that our attention is naturally drawn to the external world, and that we often neglect to look inward and reflect on our true nature. However, the Upanishads teach that through self-inquiry and introspection, one can attain spiritual knowledge and realize the true nature of the self."As long as there is duality, one sees the other as separate from oneself. But when everything has become the self, then there is no duality whatsoever" (Brihadaranyaka Upanishad 2.4.14).
