Yama, niyama, asana, pranayama, pratyahara, dharana, dhyana, samadhi. All limbs must be practiced *simultaneously* as stated in his Gita page 363 Hardback.
Yama, Niyama (akin to the 10 commandments), asana, and pranayama lead to pratyahara (withdrawal) which provide a 'meeting' ground for concentration (dharana), meditation (dhyana) and finally Samadhi. All of the above are *yagya* or sacrifice of the ego (lower self) to the will and essence of God (Higher Self or Purusha). Is this not the essence of Religion?
