Sometimes I read my old posts and they seem so 'full on'

Consciousness in a sense is quite simple, it is about how you choose to experience your world. What you believe in is reflected back to you. If you believe the world is out to get you, you will see conspiracies in every corner. If you believe you are beautiful, the world will love you. You chose your beliefs, and through them you chose how to experience life.
The spiritual journey is the journey to expand ones's consciousness, and through this expansion, create a new reality with more joy and understanding. A reality that fulfills us as human beings deeper, and makes things more meaningful.
The difference between the spiritual journey and the religious journey is that the spiritual journey does not teach what is right or wrong. It teaches you to find out for yourself. And to make your own choices. The consequences of your choices become your Karma.
