In plain words
If the attainment in question is the gaining of your own Self, then effort toward it is pointless. The whole world knows this much: a thing comes from its own causes.
Close to the Sanskrit
If accomplishment should be the obtaining of one's own Self, effort there is purposeless — because it is well known to all the world that a thing (comes) from its own causes.
