Acharya Prashant responds to a questioner who claims that with the advancement of science, the intelligence of modern man has become much sharper, rendering ancient scriptures like the Gita and Upanishads obsolete and representative of backward thinking. Acharya Prashant challenges this notion by proposing a test. He asks the questioner to gather his most intelligent, science-educated friends and, using their sharp intellect, explain the meaning of just one verse from what they consider the 'rotten, old thought' of the Upanishads. He asserts that if they can do so, he will concede that spirituality is no longer needed in the face of science, but if they fail, they should not repeat such vulgar talk. Acharya Prashant then provides a verse himself, the Shanti Path 'Om Purnamadah Purnamidam,' and extends the challenge to include even the most advanced supercomputer. He clarifies that a computer can provide a translation of the verse into any language, but it cannot explain its true meaning. He emphasizes the crucial difference between translation and meaning, stating that the meaning of such verses is beyond the grasp of science. This is because science is objective; its domain is the study of external objects. The entire world is a collection of objects that science can investigate. In contrast, spirituality is the science of the Self, the study of the subject—the 'I' or consciousness that perceives. Science, by its very definition, does not and cannot study the subject, the one who is looking. Therefore, science and spirituality are not in opposition but are complementary. Spirituality is the science of the inner world, while science deals with the external. He argues that spirituality is primary because the subject (the observer) must exist before the object (the observed). He concludes that any great scientist would respect the Upanishads, and it is only shallow individuals, who understand neither science nor spirituality, who would pit them against each other.
