Here is a song from the 1960s that has a different meaning for me now than it did then.
I thinki of advaita, which is said to mean "not two." If i insist on seeing things as a multiplicity, i had better see more than "both sides." Each "side" is likely to be a wrong side.
Of course clouds, love. life, and everything else are "illusions." My "doors of perception" are too clouded by ego, socialization, history, culture, gender, class, taste, etc. to distinguish what is Real from what isn't. I'm working on that.
