Answer:
The heart is a symbol of genuine emotions, and the eyes the conveyor of the same (as sincere feelings are communicated through the eyes). Once upon a time people used to smile and shake hands with their hearts. Though they were rooted in primitivism, the emotions they embodied were genuine. Now, in the contemporary post-colonial context, the smile is purely plastic as it reveals only the teeth. The eyes are devoid of emotion and phrased as 'ice-block.' They appear without the slightest trace of warmth and humanity. They search behind the speakers shadows, as their intentions and motives are not explicit. They are now characterized by ulterior motives. There was a time when their very greeting (shaking of hands) was heart-felt.
