It is difficult to be content because one cannot gain contentment by willpower. It is only through developing wisdom that one can be content.
the will has to have some role in developing wisdom (namely, turning itself against itself, as it were); can we say more about the limits of this role (e.g. it should not be driven by a gaining idea or spiritual materialism, etc) and how exactly it should be used (e.g. in developing wholesome qualities, abandoning unwholesome qualities, keeping sila, daily discipline in practice, etc)? what about subduing the will by taking in great art (i experience this most often with music)? it's this theravada theme of using fabrications of the personal will to get beyond its fabrications.
Contentment is in a sense a natural state but the greed and the worry lead away from it. Once we relinquish these, contentment naturally arises.
do you mean according with natural law, i.e. dhamma, brings forth contentment? Otherwise, I don't know what's natural and not natural.
I think that we have to be careful about getting different kinds of "contentment" muddled up.
Prior to the Buddha's enlightenment he remembered and reflected upon the experience of "contentment" as a child. Something was remembered that was quite simple and that had been forgotten.
this is interesting with regard to my last post. i think you're referring to when he spontaneously entered jhana, upon seeing the suffering of animals and insects while sitting under a tree (as the story goes).
