The obstacles that distract thought are disease, apathy, doubt, carelessness, indolence, dissipation, false vision, failure to attain a firm basis in yoga, and restlessness.
PatanjaliWhen you are inspired by some great purpose, some extraordinary project, all your thoughts break their bonds; your mind transcends limitations; your conscious expands in every direction; and you find yourself in a great, new and wonderful world.
Patanjali
