Shyam, if there is only darkness, slush and sewage in life we would've squirmed like worms and died. But once our soul gets a glimpse of light, then inspite of being entrapped in that darkness for centuries the desire for that light agitates us.
-- Manek Mulla in Suraj ka saatvan ghoda (Novel: Dharmvir Bhaarti, Movie: Shyam Benegal)
