Yogic practices have been practiced for thousand of years mainly for the sake of the final goal of liberation from the cycle of re-birth and the pain associated with it. These practices were intended to influence the mind more than the body. Hatha Yogis, who flourished during 15th century AD, gave more emphasis on the body. Their ultimate aim was also the same, namely attainment of the state of Samadhi. But their means were more suited to the abilities of the common man.
