If you're interested in learning more about isolating the senses in meditation, benefits & healing I invite you to check out my blog post:
If you're interested in incorporating blindfold meditation into your practice I highly recommend this one:
The MINDFOLD mask, is the same one that they used in the Superhuman: The Invisible Made Visible documentary that offers a fascinating look into how blindfolded meditation and other mind-expanding practices may help us realize our untapped human potential. This is in my top 5 favorite documentary series of all times, it shows that with practice you do not need your eyes to see and this documentary talks with children who can read and see while wearing this mask. I specifically bought this mask to test for myself if it truly is a 'blackout' mask and yes I can be sitting outside with the intense South Florida sun beating on me with this mask on and not even sense the presence of light. This is a perfect mask to add to your practice if you're truly looking to expand on your human potential intensifying your sensational connection to self.
