In these teachings, the late Buddhist nun Ayya Khema provides a comprehensive guide to meditation and spiritual development rooted in the Theravadan tradition. She emphasises that tranquillity and insight are achieved through a disciplined path involving morality, the restraint of the senses, and the systematic removal of mental hindrances. By mastering mindfulness of the body and emotions, practitioners can transition from worldly dissatisfaction toward profound states of meditative absorption. Khema explains that suffering persists because of a deep-seated craving for existence and the persistent illusion of a permanent self. Through dedicated practice, individuals learn to observe impermanence and let go of ego-attachments, eventually experiencing the liberation found in absolute reality. These sources combine practical technical instructions with philosophical analysis to help students reach their highest spiritual potential.
