Parisamvad at The Yoga Institute. Chapter 1, Sutra 30 Check this out on Chirbit Dr. Jayadeva Yogendra: "We discuss the usual kind of difficulties that come in our way and especially in our progress in yoga. We know them. They are part of our character. Disease is one. We fall sick, few times in a year. We are lazy, mind is uncertain, doubtful. Illusions, disillusionments, not finding our correct objective, goal. That kind of uncertainty, we are never a 100% sure about what we do. Various such things are mentioned. You see, these are the obstacles which are part of our personality. Even the best men have these unfortunate qualities. Naturally in learning of yoga they come as a hindrance. Suddenly doubt comes, suddenly laziness and all that. So these have been mentioned as our enemies. Unless we can overcome them, we can’t get full-heartedly into learning yoga.
