The following is an excerpt from: Who cares about Freedom?
We can go a little further too: we can also point out mistakes in our thinking. If we think Father Christmas is real, we can notice and point out there is no conclusive evidence to support that, despite appearances to the contrary (eg. presents appearing beneath the tree on Christmas Day). Any happiness or pleasure we derive from believing in Father Christmas is similarly based on our wrong notions/illusion.
Similarly, if someone takes themselves to be a doer, an entity that is free to choose and take credit and blame for its actions, then we can point out that there is no evidence to support this position, despite appearance to the contrary. All suffering that results from belief in doership is similarly based on illusion.
