[dropcap]Y[/dropcap]ou’ve probably seen this quote floating around.
Anyone can practice. Young man can practice. Old man can practice. Very old man can practice. Man who is sick, he can practice. Man who doesn’t have strength can practice. Except lazy people; lazy people can’t practice Ashtanga yoga. – Sri K. Pattabhi Jois
It sounds a lot like Jois might be citing Pancham Sinh’s 1914 translation of the Haṭhapradīpikā, 1.64:
Whether young, old or too old, sick or lean, one who discards laziness, gets success if he practises Yoga.
