re:
what the obligations mean to you?
The obligations I have said/heard/read cover three specific areas of behavior.
1) Commit yourself to improving and bettering yourself along specific moral and skill level lines.
2) Support your Brothers in doing so and do so at the level the obligation is taken.
3) Don't ruin this experience for others who have yet to have the opportunity to experience this level yet.
What do they mean? Exactly what they cover.
1) Work upon myself to improve and better, constantly.
2) Support others in doing so, and in such a way as to not harm anyone.
3) Keep things appropriately walled off and confidential.
...But I now ask myself, how much longer do I want to do this ?
If you're like me, probably for as long as engagement in it has meaning for you.
