yoga primarily deals with control of mind and thoughts using meditation with
aim of knowing the ultimate reality and to achieve Samadhi and
enlightenment. Raja Yoga aspires to control mind and thought process and for
this uses some some asanas (postures) and pranayamas (breathing
techniques) for preparing the
practitioner for meditation. Patanjali's Yoga Sutra states in the
very beginning that "Yoga control the fluctuations of the mind".
