Hello, Here is your answer -

C.V. Raman's statement that "water is the real elixir of life" can be justified by the following three points:

1. Fundamental Basis of Life: Water is the most essential component for the existence of all life forms, from the smallest microbe to human beings. It is the basis of all physiological processes like digestion, circulation, and excretion. While man has sought a divine, mythical elixir for immortality, Raman argues that the true life-giving substance is common water, without which life itself cannot be sustained for even a few days.
2. Foundation of Agriculture and Civilization: Raman observed that water creates a clear dividing line between barren desert and fertile, populated land. Water is the foundation of all agriculture. It transforms landscapes, allowing crops to grow and providing food for humanity. The rise and fall of civilizations throughout history have been directly linked to the availability of water, proving it is the true source of sustenance and prosperity.
3. Source of Natural Beauty and Charm: Beyond its role in survival, water adds immense beauty and charm to our world. Raman describes the aesthetic pleasure of looking at a rain-fed tank, a gentle stream, or even a village pond. The beauty of a waterfall, the serenity of a lake, and the grace of a river enrich the human experience and contribute to the quality of life, making it an elixir for the soul as well as the body.
