Even unconditional and passionate love can become a burden (an iron weight) both for the person loving and the person being loved' The person singing the song is admitting that her love is too intense making it a burden and all the emotional intensity drags the beloved down'..
Initially, even before Kesar realized that he was in love with Gulaal, his feelings towards her were so intense and most of the time he would end up hurting her. He lived with this confusion and turmoil for such a long time and it weighed down on him'.
Anywho, for those of you who have been missing the angry, confused Kesu...this VM is all about him...😳
