From ages past many great sages of India have devoted their entire lives to the study of the secrets of human nature and existence. They searched with inexhaustible effort and iron endurance. To attain their goal they completely withdrew themselves from the commotion of the world and concentrated all their efforts solely upon this inner quest. Ultimately, their dedicated efforts bore fruit as they experienced the Higher Truths. Thus, they understood through experience the deepest secrets of life and the mysteries of being. The Indian sages discovered a hidden, inner path leading upward to freedom and emancipation. Collectively they called it ‘Yoga’. Irrespective of sex, race, nationality and religion every one can practice yoga without any dogma and cultural belief. There exists a lot of literature on yoga in Indian classical literature. But the present study focuses its main attention on the philosophy of twenty Yogopaniṣads.
