Purpose of life is for you to live it.
I think that describes it. Truth, Love, Power are just man made concepts to guides us through our life journey. To be kind to each other, to realize how impermanent everything is, to explore this world and all it has to offer.
Life just is. You can't choose not to be born. You can't choose whether you are born with all mental and physical facilities functioning correctly. You just get thrown in and get to figure things on your own and perhaps help the others that come with you and after you.
