Lalleshwari or Lal Ded was a deeply loved mystic and poet of Kashmir. For more about her, see this earlier post.

When my mind was cleansed of impurities,
          like a mirror of its dust and dirt,
I recognized the Self in me:
When I saw Him dwelling in me,
I realized that He was the Everything
          and I was nothing.
