Translation
You are the original Personality of Godhead, the oldest, the ultimate sanctuary of this manifested cosmic world. You are the knower of everything, and You are all that is knowable. You are the supreme refuge, above the material modes. O limitless form! This whole cosmic manifestation is pervaded by You!
