Yoga as it is

How do you think what yoga is? For most it's some guy who practice strange exersice . Or may be yoga means to seat in a sacred silent place and think about something elevated? This is the way it is . Joking. Such definition we get from modern "guru".
So what is yoga indeed? Breathing and exercise are only part and helps to get aim , but not an aim as well. From sanskrit we know that yoga means " conection" . Conection between soul and God or Supersoul. Therefore yoga is not just simple gymnastic . This is spiritual process . The aim is to achive liberation not only from problem of this world , but also from this body as well. Yes , because this body is the source of different troubles. True disciple achive this by means of true master. Instead of good health etc. which can only prolonge our suffering in this body.
