From all the books I've read, from my own TYoga practice and life experiences --  all inserted into Tachy Yoga book -- I come up with the following Mind Expansions:

~  IT IS THE UNKNOWN!

~ From IT comes the mindscape existence we are in, the Being...........a Dream!

~  Tachy Yoga is the human practice to discover how deep the mindscape goes!

~  The illusion of many is mirroring the illusion of One!

~  Tachy Yoga practice is a two blades sword: one blade is cutting through the weeds of obscuration, the other weeds itself out!

~  The passionate practice is born in the heart, matures in Brahman, to turn serene back in the Pure Heart of All that IT is (Hridaya)!

~  To know is to identify with what is known! Any other way is a lie!

~  Liberation from Being brings the Real Freedom -- the Here-Everywhere Interstice of IT!
