The author conducts a thorough analysis and skillfully delves into the philosophical insights of Richard De Smet, a Christian theologian and an expert in Thomistic philosophy and Advaita Vedanta. De Smet challenges the conventional view that the Nirguṇa Brahman is impersonal. Instead, he contends that within orthodox Christian faith, the term ‘personal God’ refers to a deity without attributes—the simple Absolute (khanda, nirguṇa)—and represents pure undifferentiated truth (sad-Eva). Furthermore, De Smet upholds the personhood of both Brahman and jīvātman in Śaṅkara’s Advaita Vedanta. The author of this book deserves commendation for presenting this core truth of Advaita Vedanta in a logical and persuasive manner. Scholars and students interested in exploring the concept of person should consider this book essential.
