“But using it [yoga] for physical practice is no good, of no use – just a lot of sweating, pushing, and heavy breathing for nothing. The spiritual aspect, which is beyond the physical is the purpose of yoga. When the nervous system is purified, when your mind rests in the atman [the Self], then you can experience the true greatness of yoga.” – Jois
