The programme is very clear in suggesting that one live by spiritual principles. This is not a vague precept; it suggests that a very particular framework for life be adopted and applied. No one need adopt the programme if they do not wish to, but, if they wish to, it does impose constraints.
The main thing is that he be willing to believe in a Power greater than himself and that he live by spiritual principles.
Now, what are those spiritual principles? Clearly, the Twelve Steps, and later the Twelve Traditions and the Twelve Concepts, provide much guidance. However, even back in 1939, when the Big Book was written, these principles were very clearly established.
Some of these can make very uncomfortable reading. Two aspects are particularly jarring to the Contemporary Person. These are: the eschewal of materialism and the eschewal of particularism. The spiritual principles of the programme suggests that spiritual development must come first, ahead of material, financial, business, or professional success. They also suggest a universality of outlook, namely an actively benevolent attitude towards others, in fact, towards all, not just to those in one's circle, family, sociodemographic, religious, political, or national group but to all people. And this is not merely an empty sentiment: it should be backed up by constructive action. Here are some of the relevant quotations.

I cannot see the cause of this temptation now. But I am to learn later that it began with my desire for material success becoming greater than my interest in the welfare of my fellow man.
