The Buddha diagnosed the human condition as one of suffering due to our insatiable desire, which places us on the wheel of karma / cycle of samsara, turning continuously from one desire to the next.
Schopenhauer reified this insight by identifying will—blind ceaseless striving—as the transcendent force operative at all levels of the world as represented. The experience of our own will directly connects us to this fundamental reality.
But do we merely interpret the dynamics of the world as “will” as a consequence of our own natures as willing beings because “will” is an idea by which we have thereby been furnished?
