Tantric Meditation

As I am trying to cover all bases in this blog, I came across another reason for covering which I had not considered: that of covering the head for Yogic meditation. "breathe deep" at blogspot reports on "White Tantric Yoga", describing the setting and the conditions of the meditation, including: ". . . we're all dressed in white, with head coverings to protect the crown chakra at the top of the head." She's included a photo of another White Tantric, if you'd like to see what this looks like. I am not familiar with "protecting the crown chakra", and cannot elaborate here, but wanted to pass on the information to those who might be reading this blog, and may be interested in doing further research into this.
