This quatrain expresses the mystic's absolute devotion and internalized love for the Divine Beloved. The poet contrasts the profound internalization of love within his innermost being ('in my marrow') with a yearning to know the reciprocal aspect of the Beloved's grace ('in your skin'). The repetition of the phrase 'from head to toe' signifies both the absolute perfection of the Beloved and the mystic's all-encompassing adoration, which extends to the entire world as a reflection of that divine beauty.
