I am sure one can find many parallels in the philosophies of these two – Shankara and Plato. One such is anamnesis – recognition, remembrance, equivalent to pratyabhijña (though it seems that this last comes from Kashmir Shaivism).
Raga – attachment, passion (one of 5 constrictions (kañcuka-s) which when directed to external objects limits the sense of completion in the individual (cf. pancha-kañcuka), which resembles Plato’s Eros, similarly implying a want, a desire of completion or repletion.
“There is an ambiguity about love in its very nature. It is the offspring of Resource, its father, and Poverty or deficiency, its mother… in the Symposium [one of Plato’s Socratic dialogues] Eros signifies a want of which at the same time it is the desire of repletion. So love symbolizes or, better, manifests the actual condition of man as he exists, halfway between ignorance and wisdom.”: ‘Therapeia’- Plato´s Conception of Philosophy, Robert E. Cushman.
