In one sense, there is no need in matters of enlightenment or spirituality: people are either interested in it, or they aren't.
And those who are interested, will do what it takes.
Those that aren't interested, will don't engage with those issues at all.
Although there are peculiar groups of those who aren't interested but pretend to be; and those who are interested but pretend not to be.
IOW either you believe or don't believe.
