In the current era of Post-Truth, the concept of truth is not easily found out. Nowadays the false or fabricated appearance and ideas when presented make them appear more logical, reasonable and far widely accepted with emotional and personal belief, and appeal than the original and pure truth. Taking this concept into account, the current research paper aims to investigate how “Lord Shiva” who is worshipped by the Hindus the world over as the ‘Lord of Lords’, has been portrayed as a ‘human being’ possessing extraordinary prowess by Amish Tripathi in his first and debut novel of the Shiva Trilogy - ‘The Immortals of Meluha’. The paper examines the post-truth hidden in the evolution of myths and fables surrounding Lord Shiva and the other Indian deities and portrays the evolution of Lord Shiva as the ‘Supreme God’ from a ‘human being’ who lived centuries ago. The novel under investigation has been analysed using the Postmodern and Post-truth theories and perspectives. © 2020 Universiti Putra Malaysia. All rights reserved.
