Yoga! It means one thing in general parlance and quite another after its extensive study. Yoga—why and how—in short is the subject matter of this book. Swami Brahmeshananda, a senior monk of the Ramakrishna Order and a former editor of the Vedanta Kesari, had written a series of analytical articles on Yoga. These articles have been put together and published as this book.Each of the 19 chapters of the book can be read independently. However, reading of the book from cover to cover would give the benefit of comprehending the many facets of Yoga. The concluding chapter stresses the fact that the Bhagavad Gita is a scripture on Yoga, with each of the 18 chapters highlighting one aspect.
