When we say “yoga,” for most people it probably means twisting the body into impossible postures. That’s not what yoga is about. Among the Yoga Sutras, which form the bedrock of today’s yoga, only one sutra is dedicated to asanas. All Patanjali said was “Sthiram sukham asanam” – a posture which is comfortable and firm, that is your asana. Asanas are a very preparatory step, but unfortunately they are being propagated as the whole of yoga. Yoga means to be in perfect tune. Your body, mind and spirit and the existence are in absolute harmony. When you fine-tune yourself to a point where everything functions so beautifully within you, the best of your abilities will naturally flow out of you.
Have you noticed, just a little happiness can liberate you from your usual limitations of energy and capability. When you are happy, your energies always function better. You seem to have endless energy. It doesn’t matter even if you do not eat or sleep, you can go on and on. If a little happiness can do this to you, imagine if your body and mind were functioning in a completely different state of relaxation and a certain level of blissfulness. You would be released from so many things that most people suffer from. For example, let’s say you have a nagging headache. Your headache is not a major disease but just that throbbing pain can take all your capability away for the whole day. But with the practice of yoga, your body and mind will be kept at their highest possible peak. -”Sadhguru” Jaggi Vasudev
