I think a bright mind has nothing to do with cleverness. Really nothing.
More with honesty, one's personal 'inner work' (cleaning up moment by moment), and...what do you think?
One's drive to live, no, Live to the deepest?
My wish for (my) children.. not to become clever. Bright instead.
(In a baby's eyes and being you can see/feel this brightness (and get overwhelmed by it..) Isn't it our task to keep this spark alive in them - by doing it with our own?)
