A posture is achieved when effort stops and the mind is merging meditatively into infinity.
In morden yoga practices, we call the postures asanas. However, following Patanjali’s yoga sutras, the term asana only refers to a seated posture, literally asana meaning „seat“. This could be Padmasana (Lotus pose), or any other seated pose, with the aim to sit firm and still for a longer period of time. Obviously this is not Bharadvajasana, as in the picture!
Interestingly in the early times of yoga, any standing and dynamic postures have rather been named tapas. Studying the yoga philosophy we might find the term tapas translated as devotional austerity, but literally it means „heat“.
So, how comes that we are calling the postures asanas? Shouldn’t tapas be the better matching term for what our physical practice is today? Well, our asana practice today has at least a similar ambition – through steadiness and ease, reaching a state of moving meditation.
