"There exists at present a good deal of misconception with regard to the practices of the Haṭha Yoga. People easily believe in the stories told by those who themselves heard them second hand, and no attempt is made to find out the truth by a direct reference to any good treatise."
Whether young, old or too old, sick or lean, one who discards laziness, gets success if he practises Yoga. 2.66
Success comes to him who is engaged in the practice. How can one get success without practice; for by merely reading books on Yoga, one can never get success. 2.67
Success cannot be attained by adopting a particular dress (Veṣa). It cannot be gained by telling tales. Practice alone is the means to success. This is true, there is no doubt. 2.68
