hey free,
good for you. you have taken this opportunity to evolve yourself. just remember that expansion of consciousness continues on. atheism is the starting point of the path to enlightenment that is only yours. a totally unique path unto yourself, in the end.
you can still experience the transcendental, and merge with the infinite. but with your new tools of empirical observation and critical thinking must come a personalized balance in your mind with the magic, so-to-speak. in other words, never forget to experience the magic when it presents itself to you. these are beautiful moments that you should not pass up. however, also remember to compare it to the simplest explanation possible in order to maintain this new balance you have aquired. i believe that this is one of the keys to a happy, evolved, human life. and to this end, i would recommend a practice of focused meditation, for the purposes of centering your mind and body.
nice to meet you,
peace,
tetra
