Shortly after his arrival in India, Wood had begun translating the Indian classics, such as the "Garuda Purana". In the late 1920s, he began a thorough study of the Yoga classics with the assistance of several Hindu scholars, leading to the publication of numerous translations of famous yoga texts such as the "Bhagavad Gita", Patañjali's "Yoga Sutras", Shankara's "Viveka Chudamani". In his commentaries to these translations, Wood tried to make these texts' philosophical ideas applicable to modern life. His writings contain many references to his own practical experiences in these matters. Together with his concise treatises of yoga, such as the volume "Yoga", Penguin Books, 1959/62, and his earlier writings on concentration and memory training, Wood's works contain a complete introduction to the classic texts of Raja Yoga, or the yoga of the mind, with a sparing use of Sanskrit expressions.
