Hi
this was a question for me too a few years back
i stumbled on to a book by a french guy called Rael
his website is here and you can download the books for free

he explains all about how to awaken the mind and grow spiritually - also has some tips for the up coming events and how to train yourself for them
best wishes with your personal development
PS - just saw your quote from Ghandi, great stuff he was such an amazing light in this world
the one i like is....
An Eye for an Eye Only Makes the World Go Blind
