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.
K. Pattabhi JoisIf we practice the science of yoga, which is useful to the entire human community and which yields happiness both here and hereafter - if we practice it without fail, we will then attain physical, mental, and spiritual happiness, and our minds will flood towards the Self.
