By practicing yoga, some nondevotees keep their bodies youthful and fit, and may even achieve mystic perfections or long life. But these attainments are actually worthless, because they are perfections only of the material body. An intelligent person is therefore uninterested in this kind of process. Rather, by taking shelter of the lotus feet of the Supreme Lord, an aspiring devotee who is seriously dedicated to the Lord rids himself of all disturbances and becomes empowered to attain the highest perfection, the full bliss of spiritual life.
