There is a way to slip out of stream, into stillness, but the current dictates timing.  Mindfulness is a tool useful to determine how to slip out regardless.  When our arms strain, are weak or sore, we can draw focus toward the mind–the place where will is stored–and be.  That is stillness.  We are not our bodies, so we possess the strength to melt into them and dissolve into being, even when the waves rush past and splash us in the face.  Mindfulness is connected to divinity, therefore it is timeless.  In the stream, we struggle to connect, but as long as we inhabit these bodies, we embody the power to turn inward, smile and be.  That is freedom.  That is timelessness.  Sometimes knowing you have the power is enough to enact it.
