When we are in harmony and in bliss, time vanishes or passes very fast. Time flies. But once the baby bottle is removed from its mouth, the baby cries and desires to continue suckling the blissful amrit.

Pangs of separation land us in a 'prison' where time indeed does not move. Days seem like months. Guru Nanak wrote :

ਸੰਜੋਗੁ ਵਿਜੋਗੁ ਦੁਇ ਕਾਰ ਚਲਾਵਹਿ ਲੇਖੇ ਆਵਹਿ ਭਾਗ ॥
संजोगु विजोगु दुइ कार चलावहि लेखे आवहि भाग ॥
Sanjog vijog ḏu*ė kār cẖalāveh lėkẖė āvahi bẖāg.
Union with Him, and separation from Him, come by His Will. We come to receive what is written in our destiny.
Guru Nanak Dev - view Shabad/Paurhi/Salok
