While people, the world over, are generally acquainted with the word 'Yoga', there are perhaps as many ideas and definitions of Yoga as there are minds in the world. It is often said that there is a world under every hat. Each person has his own conception of what Yoga is, sometimes overemphasised, sometimes under-estimated, sometimes misconstrued, and oftentimes deliberately misrepresented for reasons or motives of one's own. But, seekers of what they call 'Perfection' would do well to take things seriously, and not dabble with the subject as a sociological problem, or something that will win wealth, name and fame.
Yoga is something which is dear to all.
Nothing can be dearer to man than Yoga, if one can know what it really means. It is not merely a subject that one may choose for one's studies, as in a college, for the purpose of a pass or a degree. There is a glib definition of Yoga as 'union', an offhand description of it with which we are all familiar. But it is not easily known as to what this union is about, and who is going to be united with what. And what for is this union, is also a kind of doubt that will occur to our minds.
