In plain words
Letter by letter I come, hands joined, falling at the Lord's feet, and beg Him: why is it so long in coming, the one-pointed devotion that should rise within me? Hari, salutation to Nārāyaṇa.
Word for word
From the letter ḹ onward I too here, with joined hands, falling down, beg the Lord at once: why the delay for single-minded devotion to come and rise within? Hari, salutation to Nārāyaṇa.
