The philosophy of Yoga tells us that the root cause of our sorrows and suffering is loss of contact with our true Self. Our recovery is only possible by re-establishing contact with our innermost Self, the Reality of all realities and by recognising that knowledge of Self is our salvation. In this comprehensive guide, Swami Adiswarananda introduces the four spiritual paths of Yoga - Karma-Yoga, Bhakti-Yoga, Raja-Yoga and Jnana-Yoga - and what you can expect as an aspirant on each path. Covering the message and practice of each of the yogas as well as philosophy and psychology, preparatory practices, common obstacles and ways to overcome them, this accessible book will prove invaluable to anyone wishing to follow a Yoga practice in order to realise the goal of Self-knowledge.
