What it means to be in the presence of a Master

Have you ever observed your mind when you gaze at a vast ocean, or a huge mountain, or the infinite blue sky? The chattering mind, scattered and wrecked by thoughts, suddenly becomes quiet. A deep silence fills the being, and everything else in the world loses its relevance. It's the same way you feel when you meet a Master. You might go to Him with 100s of questions in your mind, but the moment you stumble into His presence, all questions drop, desires vanish, and the mind dissolves, as if it has merged into Infinity. And in case He happens to gaze into your eyes, even if for the minutest fraction of a second, something beyond the ordinary happens. You experience a bliss that is beyond measure, a joy that cannot be explained in words, and supreme love, that they say even angels long for. 

This couplet by Amjad Islam Amjad so aptly describes what it means to be in the presence of a Master:

"Meri umra se na simat sake, mere dil me itne sawaaal the,
Tere paas jitne jawaab the, teri ek nigaah me aa gaye!"

Which translated into English means:
In my lifetime I could not gather all the questions that I had. But all the answers that you had, in just your one glance got revealed. (you may read the whole poem here)

So if you ever get a chance to be in the presence of a Master, don't think about what you will ask Him, or what will He say to you. Just know that when that moment comes, your silence will speak louder than your words....and so will His.
