Explanation:

Krishna used this word in the Gita (Anaadimat param brahma…) and Shankara also used it in His prayer (Maunamvyaakhyaa prakatita Parabrahma…—Dakshinamurti Stotram) and hence, this word is quite ancient. You need not reject this word just because it is used by a modern person like Datta Swami. Generally, people give value to ancient sages and not to modern preachers. However, this is not correct. We should analyze the concept and decide its value. A modern preacher like Shri Ramakrishna Paramahamsa is a good authority. The ancient sage, Charvaka, who propagated atheism, is not an authority. The author tries to satisfy the blind psychology of people regarding their taste for ancient sages through this Sutra, although analysis of the concept is the real ultimatum.
