Positive mind refers to your creative expansive mind as described in
'the mind book' by yogi bhajan* and
I found the book useful. It begins by breaking down the mind into its positive(+),
negative(-), and neutral(0) tendencies. It is a great map for meditation.
What ever you do in life or what ever your
religious (un)beliefs I whole heartedly believe that without a meditative practice you're living life as a pinball or pachinko ball being bounced around by the game of life.
You have no idea how turbulent your mind is until you stop and work with it in meditation. Life is smoother with meditation as you start to consciously navigate the board rather
than be steered by your subconscious habits. It's an incredible amount of work, but by far the most worthwhile activity. I recommend developing your practice cautiously in a grounded organic fashion.
Throughout the site you'll find thoughts on yoga and tunes from reality a music project
(consider supporting independent music by buying
a CD-R). Give the akara numerology readings a try, for fun if nothing else.
