[QUOTE=Surya Deva;51167]Amir is right. Meditation is not the same as contemplation, rather it is the opposite of contemplation, where a state is created which is absent of all thought. If one is thinking during meditation they are not meditating. This is why meditation is often described as a listening or watching activity. You listen and watch what is going on in your mind without thinking about it.
It is possible to meditate in shavasana, but difficult. Most yoga instructers advise one not to meditate in shavasana because the posture can induce sleep quite easily. This posture is deliberaly used in another Yogic practice called Yoga Nidra(Yogic sleep) to deeply relax the body. The aim of meditation is not to relax your body completely, but rather to remain alert and watchful of what is happening in your mind. Thus they serve different functions.[/QUOTE]
Yoga meditation is concentration on God. Putting the body to sleep while keeping the mind awake is just about the only way I know of to enter in into Pratyahara. Even then you can still hear, but the sounds are muted. Once you are in this state your concentration isn’t nearly as easily broken. When that concentration is focused solley on God, or Om, or any aspect of God it becomes meditation. All the fancy semantics are silly.
Meditation also means to sit and watch you breath. It also means to sit and observe your thoughts. It also mean sit focus on the space around you.
Arguing over this would be like Organic Chemists trying to reclaim the word organic.
Meditation has a lot of meanings today, but in yoga meditation means perfect concentration on God. IMHO. Thus the the word Yoga which means Union.
But hey keep worrying about all the details… instead of focusing on the only thing that matters…figuring out what you are.
