This preface introduces "The Philosophical and Religious Lectures of Swami Vivekananda," the second volume in a series dedicated to the Swami’s teachings. Following the success of the first volume on the Four Yogas, this book condenses Vivekananda’s lectures to one-third of their original length, utilizing paragraph headings to enhance readability and clarity.

The core objective of these lectures is the practical application of Vedanta to modern life. A central theme is the inseparable bond between philosophy and religion in the Indian tradition. By providing a rational, universal justification for spiritual values, the text transcends specific creeds. Ultimately, these lectures aim to help followers of any faith deepen their spiritual understanding through a Vedantic framework that is both ennobling and intellectually rigorous.
