I think it is possible to confuse a positive psychological effect in the sense of bringing you joy as opposed to a positive psychological effect that results in improved communal activity. I mean to say, not all benefits to a community are coincident with benefits to the individual. In fact, that would be a pretty Christian idea, that the sacrifice you make as an individual (to your enjoyment) results in a benefit for the community. That is what I meant about me feeling selfish. It may be the case I am prioritizing my comfort over the needs of the community. Rituals are a public display of a willingness to sacrifice, one that is shared amongst a community. The monks see themselves sacrificing for the sake of each other when they show up for the unpleasant 5am prayers.
