Have you ever felt the heaviness, not just in your heart but inside your mind, when you realise that a person you are meeting at the instant, is the last time you will meet them? I have felt it so mant times, it happens with persons I form a sort of a bond a connection deeper than the normal transactional relationships one has.
The feeling is more profound when you "know" that this is the last time, and maybe you will never again meet the person in life. The entire world at that moment seems so big, so full of probabilities even in today's world of instant communication. You may even exchange contact information and promise to be connected, but in your heart you (and the person) knows that these are just formalities. Your heart is sombre not wanting to let go the moment, but then time never runs slow when you want it to.
There is also a classical twist in the tale. If you do ever, bump into the person after many years, the situation could be so different then, that the past memories hold no value in the current context.
But unless that happens we keep the probability of meeting again, "just in case"! "Shaayad"
Which brings me to Ahmed Faraz:
फिर उसी रहगुज़ार पर शायद,
हम कभी मिल सकें मगर शायद।
And of course, JS makes it heavenly, especially when he mixes Waris Shah's "Heer".
The ghazal by Faraz, is a short syllable marvel at 10 syllables.
The beher (meter) of the ghazal is: 2122-1212-22 (often used with 2122-1212-112)
