When we're listening to some shabad , and the harmony of harmoniums, and other musical instruments with the shabad make that perfect sound , and when at same time you have yearning in your mind "O lord !" and your eyes well up with tear and soon run down the cheeks . Its as if for a split second , you feel him in everything. What is this ? Is my mind playing tricks or is it his bliss akin to split-second lightening in the otherwise dark sky.
