On principle, one could do that simply from reading literature too, as much literature is narrated from a perspective assuming itself to be omniscient. This could help one develop self-reflexive faculties and according practices. In fact, this is one of the arguments given for why especially youths should read literature (esp. fiction). But, to connect again to what Bhikkhu Bodhi has been saying - unless there is a conviction in some kind of "higher power", in some kind of objective reality that contextualizes the individual, some recognition that ethics aren't simply subjective, personal, individual, private, but that there is an objective right and wrong, an objective "how things should be" (or at least an objective "how things should be if a particular goal is to be attained"), consequent individualism simply leads to what is in effect solipsism.
