How can someone living in the world practice Yoga science? If you understand the fundamental principles of Yoga science and why Yoga science should be practiced, it will become easy for you to practice. First you have to decide to search. You have to feel the necessity of finding yourself. Yes, I want to know myself. Something is missing, something I could not receive from my church, from my religion. Millions of people, both in the East and in the West, are searching for Truth and Self-realization—or as the religionists put it, God. You may go to church or temple or synagogues, but the questioning mind is still there. Sometimes orthodox religions do not satisfy your needs, so you question life. When your mind questions, it means you are not fully satisfied. Life is a question in front of you. You want to know something more, but you are using this little mind, which is like a yardstick, to measure the vast universe and its mysteries. You do not understand your religion because you do not understand yourself.
