In plain words
The poet, to the Lord of Araṅgam: My Father, who that day [as Trivikrama] strode across all the worlds and set your foot on every head, red-eyed Māl who loves his own: I will worship no one but you, firmly and always. My breath, my nectar, my Father who is like my own precious life: sinner that I am, I will think of no one but you. A sinner I am!
