A very nice article by Sadhguru that I thought I would share, every detail of our practice has to be considered, no stone left unturned everything has relevance and should be thought about.
Sadhguru looks at the importance of the right kind of clothing during sadhana, and the need to avoid metallic objects on the body at this time.
Sadhguru: When I did hata yoga as a young boy, the only thing we were allowed to wear was a small loincloth. The idea was that there should be as little obstruction as possible. Traditionally in India, people did not wear stitched clothing. Both the dhotis for men and the saris for women are just pieces of unstitched cloth. When clothing is stitched, the movement of energy gets restricted to some extent – you want to minimize that when doing sadhana. This does not mean that you need to start wearing a loin cloth, but yoga practitioners should not wear synthetic clothing such as the kind that athletes wear. It is best if your clothing is organic – either cotton or raw silk. Since organic raw silk may be too expensive and difficult to get, organic cotton would be the best option. Wool is all right too.
Before starting your sadhana, you should remove any objects from your body, especially metal ones. If you take an image of electromagnetic waves, even a small object will create a certain circulation around itself. If you put any object on your body, it will tend to disturb the free movement of energy. Except for a few parts of the body that are dormant, like the earlobes, any kind of metal should be removed – even nose studs. Only your rudraksh and the snake ring, you can keep on. Rudraksh is a good support that creates a cocoon of your own energy and makes you available to grace. The snake-ring because it prevents the one-in-a-million chance that you accidentally slip out of your body when you do certain sadhana. For women, if you are using any kind of metallic clips on your spine, that should go. Plastic is better than metal in terms of energy.
For the practices, you must remove your spectacles too. Many people have gotten rid of their glasses through the practice of proper yoga. For your vision to correct itself, you need to avoid wearing glasses or contact lenses for some time. If you can manage without glasses or contact lenses, try to do so. In case you get headaches, spend more time with eyes closed. If you are using contact lenses, do at least your morning sadhana without them. That way, mild vision problems may improve over a period of time.
I was brought aware of the teachings of Sadhguru some time ago and was so grateful of this charismatic man. I look forward to hearing more from him in the future and a dream to visit his ashram one day. For now let us consider what we are wearing for our practice more in terms of not what we are looking like but what it means in terms of energy and how that effects us.
Have beautiful days
