yoga has evolved over thousands of years.
Around 200 BC, in order to attain a state of 'yoga', the renowned sage
Pantanjali, determined a series of steps, based on "eight limbs"
or Ashtanga. This exalted state of self-realization derives from a union
of mind, body and soul, with all distractions to taking control of the mind
removed. The "third limb", or Asana, that is the practice of
yoga postures, is at the heart of Ashtanga yoga teaching to this day and
emphasizes the role of the breath in focusing the mind.
