In the selected passage, the lotus is not simply an ornament in a scene. It gives the poet an image for the devotee’s heart, and the divine lamp-light places Murugan within that image. The wording joins affection, life and illumination in a single act of praise.
It would be too narrow to treat this only as an instruction to relax. The passage belongs within an extended devotional and philosophical poem. A quiet personal reflection can accompany the reading, while the fuller explanation continues to ask what its language means within the work.
