““Those who really want to be Yogis must give up, once for all, this nibbling at things. Take up one idea. Make that one idea your life — think of it, dream of it, live on that idea. Let the brain, muscles, nerves, every part of your body, be full of that idea, and just leave every other idea alone. This is the way to success, and this is the way great spiritual giants are produced. Others are mere talking machines. If we really want to be blessed, and make others blessed, we must go deeper. The first step is not to disturb the mind, not to associate with persons whose ideas are disturbing. All of you know that certain persons, certain places, certain foods, repel you. Avoid them; and those who want to go to the highest, must avoid all company, good or bad. Practise hard; whether you live or die does not matter. You have to plunge in and work, without thinking of the result. If you are brave enough, in six months you will be a perfect Yogi. But those who take up just a bit of it and a little of everything else make no progress. It is of no use simply to take a course of lessons. To those who are full of Tamas, ignorant and dull — those whose minds never get fixed on any idea, who only crave for something to amuse them — religion and philosophy are simply objects of entertainment. These are the unpersevering. They hear a talk, think it very nice, and then go home and forget all about it. To succeed, you must have tremendous perseverance, tremendous will. "I will drink the ocean," says the persevering soul, "at my will mountains will crumble up." Have that sort of energy, that sort of will, work hard, and you will reach the goal.””
