Close. Agnostic can cover two or three variations viz.
- people who believe there is no God or super being
- people who believe it is not possible for us to know whether there is or not
- people who believe in all versions of it
@Sainthood 101 all three above cases, it is possible for a person, and I know such people, who follow the moralistic and behavioral aspects of some religion for such behavior itself to be the end rather than them being a means to reach or realize a God.
Think of it as solving an algebra problem. We introduce an unknown variable X, go through the calculations and at the end the X disappears giving way to a contextual answer such as 18kg or 24 feet or 3 days etc. We can arrive at these answers without an X but it becomes much easier with an assumed variable X.
...... now to top all that of, we can ask ourselves the next question : so in the above , did X exist or not ? That'd lead us to some deep advaita territory so I'll have mercy on you and stop !
