Ditto on what Really?! said!
Yoga along with its meditations and chantimg opens your mind! The meditative part requires you to still your mind and empty your thoughts and be STILL! So no! The WTBS doesn't want you to do that, in fact they've always told us to "meditate on the things learned" which fills your mind with constant THOUGHT!
A still mind also allows you to hear that inner voice and whatever questions you may have. You start to have questions you start to get answers. They don't want you to get answers as they tap into your true spirituality, who you really are!
I love yoga and meditation, it's a daily practice for me. There are so many good results in it for your over all health and well being. You're more peaceful, calm and happier. You have a deeper connection to whatever IT is out there, hence you don't need the middle man.
so heck no they don't want you to go there.
