Duality is the dynamic aspect of the non-dual, or Final Cause. Inseparable, like the mirror and its images. Yet the former remains unchanged and the latter stays in a constant state of flux.
If you try to love all things you will come up short. Rather, fall in love with the source of all things and you will see your Beloved in the midst of all human activity and emotion. From the most pleasurable to the most painful. In deep anxiety and in deep joy.
Unless a seeker is able to live a normal life and credit all phenomenon to the Final Cause it can’t be said that the supreme goal is reached.
