Paramahansa Yogananda (1893–1952) was an esteemed spiritual teacher and an early proponent of the harmony between Eastern spirituality and Western material progress. Born Mukunda Lal Ghosh in Gorakhpur, India, Yogananda became a monk in the ancient monastic Swami Order and acquired his better-known monastic name. His literary contributions offer a blend of personal narrative, spiritual insights, and practical instruction. Chief among his works is the seminal 'Autobiography of a Yogi' (1946), a beloved spiritual classic that continues to inspire seekers worldwide with its deep teachings on Kriya Yoga and the path to self-realization. In 'Scientific Healing Affirmations' (1924), Yogananda elucidates the potent use of affirmative prayer and the power of thought to effect physical and emotional healing. This work encapsulates his philosophical approach that merges scientific principles with spiritual practices, aiming to uplift the human condition through methodical affirmation techniques. Yogananda's literary style is characterized by its poetic richness, metaphysical depth, and an appeal to rational inquiry. By interweaving anecdotes from his own illuminative experiences with timeless Vedic wisdom, he presents spirituality as both an esoteric and practical discipline. His teachings and writings led to the establishment of the Self-Realization Fellowship, an organization dedicated to disseminating his principles for spiritual living and meditation. Through his literary legacy and global influence, Paramahansa Yogananda remains a pivotal figure in the dissemination of yogic principles and the broader conversation regarding spirituality and science in the modern era.
