You might then pursue some spiritual practices, usually on your own, maybe in secret, and maybe only at certain times or under certain circumstances.
But then at some point, you come to realize, you literally cannot become any more spiritual in isolation without bringing the isolation itself into question. The compartmentalization of your spirituality into a little box also has to be reconsidered. And when you allow yourself to 'get spiritual' or connect with Spirit has to shift from 'only when its really needed' to 'all the time'.
So then, it occurs to you, that to move forward in your awakening, you have to open up your spirituality to be more inclusive. You can't continue to have certain pockets of the world that you don't forgive. You can't keep certain people in the dog house forever. You can't withhold forgiveness from key individuals that you especially can't get over. And what you are attempting to access through your spirituality is opening up into an inclusive, shared oneness, which means it is surpassing the boundaries you set up.
So now to go further, you have to realize, as ACIM says, that you have to see everyone as Christ in order to see it in yourself. You have to forgive everyone to forgive yourself. "What you do unto the least of my brothers you do unto me" - Jesus. What you do to one member of the sonship you do to everyone. And what you are entering into as you advance is actually a SHARED spirituality where your identity is actually ONE with other people. Equality. Christ consciousness. Sonship/one-ship.
So at some point you have to confront all of the reasons why you want to keep your spirituality in a box, in order to progress further. You can no longer withhold love and forgiveness from those special-hate candidates. You can no longer think about your awakening as something that happens to you AND NOT other people. You can no longer see yourself as being ABLE to wake up `in isolation` to the exclusion of everyone else. You are waking up TO everyone being awake.
As the course says, we all wake up together. And as Jesus says in the course, until He awoke, the entire sonship was in darkness. And when he awoke, because he was a part of the sonship, the entire sonship woke up as one. And also because Jesus is part of the sonship, this absolutely means (this came to me last night) that Jesus is 100% included in your awakening and will be a PART OF YOU and is actually going to be fully present with you as part of the sonship - he's not just some occasional drop-in that goes away and hides behind a mind-cloud.
No stone left unturned. No person left unforgiven. No grievance left undone. No fear left uncorrected. No love left unshared.
