OK, I was unaware how long you had been practising - 11 weeks or 11 years. That's the problem discussing with a just few snippets of text to go on.
I don't think Aspergers precludes any Zen practice, however if I can make an observation, you seem to be bogged down in finite details "8 Freedoms, the 10 Endowments". It reminds me of my days as a monk. One of my peers, a young German man learned Sanskrit in a deep scholarly way so he could read ancient manuscripts in the original, he was very logical and a devil for all the details and very serious all of the time. Looking back I think he may have been an Aspie. Another young man spent more of his time in meditation and was very passionate in a non-scholarly way. I think as Aspies we have a tendency to over-analyse and collect knowledge rather than simply look, and be the witness. We play games with words in our mind and build them into concepts of obstacles. Enlightenment is something "out there", some distant concept rather than here, now and we think that we need to learn more facts and accumulate bits of knowledge than to see beyond knowledge itself.
Why worry about compassion? Why make it a plaything of the mind? As aspies we are not unfeeling, sometimes it seems to be the opposite in fact, merely that we cannot pick up on another body language as easily, but we still feel empathy for their pain and suffering. I sometimes see mothers carrying their dead child in some war zone on the television news - and I am that mother. Maybe you will become a bodhisattva maybe not. Why preoccupy your thoughts with such things - from where does the desire to become a bodhisattva arise?
I don't know if any of this helps. Personally I have let go of the details and making distinctions between this path or that path and choosing. Now I simply look, see what is and have no need of a teacher, they only give me more words and concepts for the mind to play with. One can either use one's own eyes and look; or hear endless descriptions by others on what it means to look and see. If you feel you need a teacher then that is fine too, all part of the game
There is a Zen group on the beliefnet website, maybe they can be of assistance to you? I no longer participate in the group but I think it is still quite active. There is similarly a Zen group on Usenet but that tends to be bogged down by spam and trolls - I never found it particularly helpful.
Best wishes with your spiritual search.
