The Dark Beloved (Sanwal): The term "Sanwal" refers to a beloved with a dusky or tan complexion. In South Asian poetry, this is a direct reference to Krishna (the divine lover) or, in Sufi tradition, the spiritual guide (Murshid) or God, whose beauty is earthy and captivating.
Total Consumption by Love (Loon Loon): The phrase "Loon Loon" (or Rom Rom) refers to every single hair on the body or every pore. The poet isn't just sad mentally; their entire physical and spiritual being is screaming in anguish for the beloved. This represents a state of total immersion in love where the separation is felt physically.
The Pain of Separation (Viraha): The song captures the classic theme of "Viraha" (longing in separation). The protagonist feels that without the beloved, life has lost its meaning ("Meri jindri hoye udaas") and there is no peace ("Chain qaraar").
Surrender and Loss: The final verse speaks of losing everything in the path of love ("Sab kuch haar"). In Sufism, this "loss" is often a necessary step—one must lose their ego and worldly attachments to truly find the Divine, even if it comes with immense pain and perceived betrayal ("Harjayee" - though here it likely refers to the beloved's seeming indifference).
