There are three types of disease: body disease, mind disease, and nervous system disease. When the mind is diseased, the whole body is diseased. The yoga scriptures say “Manayeva manu ā ā kara a bandha mok ayo (this verse may be transliterated incorrectly),” the mind is the cause of both bondage and liberation. If the mind is sick and sad, the whole body gets sick, and all is finished. So first you must give medicine to the mind. Mind medicine: that is yoga.

It is very important to understand yoga philosophy: without philosophy, practice is not good, and yoga practice is the starting place for yoga philosophy. Mixing both is actually the best.

The full ashtanga system practiced with devotion leads to freedom within one's heart.

Yoga is for internal cleansing, not external exercising. Yoga means true self-knowledge.

Yoga, as a way of life and a philosophy, can be practiced by anyone with inclination to undertake it, for yoga belongs to humanity as a whole. It is not the property of any one group or any one individual, but can be followed by any and all, in any corner of the globe, regardless of class, creed or religion.

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.
