When Henr y Miller, the American author, decides to take a year - long road trip across the United States in 1939, after returning from Paris, he lodges a scathing attack on the gradual transformation of America into what Miller calls an “air conditioned nightmare” in the eponymous book which is a sui generis. In critiquing American tendencies of consumerism, Miller takes recourse to Indian philosophy and refers extensively to the teachings of Indian mystic Ramakrishna, his disciple Swami Vivekananda and also Jeddu Krishnamurthi. By alluding to these spiritual masters Miller attempts to provide an escape route for America to regain a kind of (in)humanity where all life converges into a disparate whole, channelised by one’s elan vital or life rhythm. It is interesting to study how Miller ’s works like Air Conditioned Nightmare and his semiautobiographical novels like Tropic of Cancer and Sexus can be seen through a postcolonial lens to show how Miller departs from ‘colonial’ notions of transcendence as a religious function and synthesizes diverse mystical traditions of thought into an immanent category of experience to first critique and then provide solutions to what Miller interprets as problems of modernity , which reduces man to his machinic function. This paper shall ar gue how in Miller ’s somewhat desacralised notion of mysticism, all facets of life including sex, animalistic behaviour, aggression, femininity , find place and converge as a decentred whole. In forging the world of his fancy he excludes nothing which is the immanent approach in Page 90  Labyrinth: ISSN 0976-0814 (Vol.10 - No.2, April 2019) Indian philosophy , towards a kind of embodiment of a very urban mystical experience where transformations of various kinds are always underway , which might answer some vital questions of modernity . Miller’s careful choosing of a uniqu e line of poets and artists like Whitman and Rimbaud who ’ve emphasized on the body as the site of all transcendental experience, along with the mystical immanence found in Indian philosophical approaches, is unique in American literature. This also makes M iller a champion of early postcolonialism. By employing mysticism as a method of embodying all experience Miller rescues transcendentalist philosophy from the trappings and hierarchies of various colonial interpretations, making him an early champion of de colonisation
