" 'Those who wish to rise to the platform of yogic perfection practice the yoga system and strictly follow its regulative principles. They practice the yoga postures, āsanas and breathing exercises. Those who are already elevated to this platform practice meditation and keep their minds on the Supreme Lord. They reject all material activity and keep their minds in an equipoised condition [śama].
