Translation:What is tea? What is water? Who am I?
Yo. That is fine. I love Indian philosophy. I have read the Bhagavad Gita, studied the Mahabharata and the Yoga Sutras of Patanjali. This is why I want to learn Hindi and Sanskrit. But as part of one of the first lessons, we don't understand enough yet to get into philosophical statements such as "What is tea? What is water? Who am I?" I LOVE INDIAN PHILOSOPHY, but as a beginner student, I was afraid that I was misunderstanding what I thought would be a beginner level statement. Better to keep it simple... at first....
Actually This is something of Object Oriented Ontology (the "new" rave in the west) integrated in various Indian Philosophical texts. This is in contrast to the descartes, aristotle, plato thinking of "everything exists in the mind". This philosophy explores the world not as a subject of the human mind but as independent entities with their own characteristics only a part of which the human mind can perceive.
memory loss works in strange ways. There are different types of memories, emotional, functional, long term, short term etc. Sometimes, during memory loss, people forget their native tongues and remember very clearly other languages they have learned. There are actual cases of people speaking in a language they had never officially learnt but had picked un subconsciously while watching movies in foreign language with english subtitles or listening to music etc. Human mind is a very strange thing. You never know!
