The separated woman is likely counting the days. She makes her final auspicious mark (tilak) by mixing her tears with the vermilion paste.

This couplet paints a poignant picture of a woman separated from her beloved. She is counting each passing day, consumed by her longing and anticipation for their reunion. In a deeply emotional moment, she takes the vermilion from her kankavati box and mixes it with her own tears. With this sorrowful blend, she applies her 'last tilak.' This act is laden with profound emotion, symbolizing her immense grief, perhaps a final blessing for her partner embarking on a journey, or a desperate gesture of unwavering devotion amidst the pain of farewell and separation. It beautifully captures her deep love and profound sadness.
