In plain words

Homage to Dakshinamurti, whose grace is cooling and kind. Tamil explanatory prose: The five elements, sun, moon and living person are his eightfold form. Enquiry reveals the supreme reality pervading all, with nothing outside it. Salutations to Dakshinamurti, the peaceful Guru, sacred grace embodied.
Word for word
Earth, water, fire, air, space, moon, sun and the person: this whole of the moving and unmoving is His eightfold form. To those who reflect, He is the all-pervading Lord, apart from whom not the least other exists. Homage to that Dakshinamurti, the Guru of cooling grace.
