These words of Shaikh Abul Hassan Kharqani illustrate very aptly the thoughts of Hazrat Inayat Khan on the purity of life. For more about Abul Hassan, see this post.
There is a light that shines from the Lord onto humanity,
and that is the light of Grace.
There is a light that seeks its way from humans to the Lord,
and that is the light of Purity.
