“Atma-Vidya”, or knowledge of self, is humanity’s eternal quest. Through the understanding of Atman, one can get ever-lasting peace and immense happiness. Adi Shankaracharya explains the Advaita philosophy of understanding Ātman through a short yet enlightening text called “Manisha Panchakam”. This book written by Dr. B Mahadevan, a retired professor in Indian Institute of Management, Bangalore, highlights the urge to pursue oneness with self, society and the world for ultimate liberation and joy. The book addresses modern societal challenges, accommodation, and unity. It encourages readers to contemplate and embrace oneness, discovering common threads among people and living sustainably. Among the eight chapters in the book, the introductory chapter establishes the importance of oneness in a world characterised by discrimination, differentiation, and selfish tendencies. The rest of the book is organised chapter-wise with each shloka forming the base for a chapter. The book concludes with the concept of eternal happiness and the nature of that happiness and establishes how Manisha Panchakam leads the ardent reader and contemplator to the path of liberation.
