For example, while you're reading this, you're focused on what you're reading, but on some level you're aware of the room you're in and that the earth is round etc. This is important, because, though we can be aware of the illusory nature of the maya--and may other things on many other dimensions--we must function within our paradigms--milk the cows, pay the rent, avoid accidents, care for our children, study for exams.
It is also important not to confuse this with moral relativism. When we're functioning in the paradigm of everyday life--or in any paradigm for that matter--it is important to make sound decisions, including moral decisions. In fact, each of us is responsible for his own behavior and destiny. Certainly no one else is.
