The Psychology of the Yogas explores the dissonance between the promises of the yogic quest and psychological states of crisis. Western practitioners of yoga and meditation who have embarked upon years-long spiritual quests and who have practiced under the guidance of a guru tell of profound and ongoing experiences of love, compassion and clarity: the peaks of spiritual fulfillment. However, after returning to the West, they reported difficulties and crises in different areas of their lives. Why did these practitioners, who had apparently touched the heights of fulfillment, still suffer from these crises? The author explores the psychological theory of yoga and its concrete yogic psychological methods such as 'cultivating of the opposite' (pratipaksa bhavana), transforming it to 'imagining the opposite', a practice aimed at healing negative habitual tendencies. These methods are extracted from an in-depth study of the Yoga of Patanjali and the Tibetan-Buddhist Ati-Yoga of Longchenpa - the Dzogchen. The works of Patanjali (3rd century) and Longchenpa, (14th century) provide a profound psychological framework for understanding the human psyche. These methods are effective but at times difficult to implement. However, as demonstrated through a case study Western psychology can effectively undo habitual tendencies in a manner which may complement yoga practice, enhancing the integration of one's spirituality and psychology.
