Sūta said: He who practises yoga never suffers calamity. When the prāṇa is properly trained it turns the defects of the mind, speech or body, preserving the body of the practIser. Thus, if the devotee perfects himself by taking recourse to the prāṇāyāma his defects perish; the very breath is conquered by him, and the divine quiescence etc. are achieved.
