The volume explores the many facets of the I-consciousness that pervades the states of sleep, dream and wakefulness that encompasses our lives and makes a person view his life as different from the lives of others. It studies the notion of I-consciousness as found in different strands of philosophical thought in India and the West. Referring to the Upanishadic tradition, the Buddhist tradition and others, it addresses the paradox of permanence and mutability of life and delves into the subjectivity of its interactions.
