The writings and lectures of Swami Vivekananda on meditation, its advantages, and its practices are collected in this book. It is a book that offers lessons drawn from Swami Vivekananda's life to help audiences navigate their own personal turbulence. According to Swami Ji, meditation should be unfavorable. Consider everything. By using your will alone, analyze anything that comes to mind. Next, declare ourselves and what we truly are: beings of existence, wisdom, and happiness. His entire philosophy on meditation and its practices is covered in this book.

What Hinduism needed, amidst the general disintegration of the modern era, was a rock where she could lie at anchor, an authoritative utterance in which she might recognize her self. And this was given to her in the words and writings of the Swami Vivekananda.

The goal of mankind is knowledge. That is the one ideal placed before us by Eastern philosophy. Pleasure is not the goal of man, but knowledge. Pleasure and happiness come to an end. It is a mistake to suppose that pleasure is the goal. The cause of all the miseries we have in the world is that men foolishly think pleasure to be the ideal for which to strive. After a time, man finds it is not happiness, but knowledge, toward which he is going, that both pleasure and pain are great teachers, and that he learns as much from evil as from good.

Raja Yoga contains transcripts of lectures by Vivekananda on "Raja Yoga", his interpretation of Patanjali's Yoga Sutras, and a "rather free translation" of Patanjali's Yoga Sutras plus Vivekananda's commentaries, which also was a series of talks. It presents Vivekananda's understanding and interpretation of Patanjali's Yoga Sutras, "and a selection of hathayoga teachings on the basis of the beliefs that he shared with his students." These included elements from traditional Hinduism, but also ideas from Western science.

Bhakti yoga is a real, genuine search after the Lord, a search beginning, continuing, and ending in love. One single moment of the madness of extreme love to God brings us eternal freedom. “Bhakti is greater than karma, greater than yoga, because these are intended for an object in view, while Bhakti is its own fruition, its own means, and its own end.”
