Inward / Outward is illusion, like all other duality, cause the nature is unity, there is nothink that can exist without his neighbor, there is no division. Like a 0 that cant be devided...
To see it, we must be more attentif about correlations between the mouvement of our thoughts, and the mouvement of our lifes, when the first correlation will be seen and after developped, inward/outward duality disapears, and when it's disapears you can play in life, when you tired to play a GTA with the limitless codes, you will ask your self the question... "It's pretty good game, but how get out? How to finish it?"
Is a good method to keep awereness in the daily life. You just try to remark the correlations between your past thoughts and the present moment.
Like a little kitty in front off a mirrow, he dont remark the correlations between his body and that he see in mirrow. He think that is an another kitty, so duality arise in his mind.
PS: Dont take this message litteraly, it's an image. And by saying 'you' i mean 'the one'
