Someone reminded me of this the other day, and I had to go find it...
I was reading The Diary of Juliet Thompson just now, and I came across this little bit that reminded me of our conversation. She was a Baha'i who lived during the time of 'Abdu'l-Baha, and she spent a good deal of time with Him, talking with him, learning from his example of selfless service and love for humanity... Juliet was in love with a Christian preacher called Percy Graves who wasn't the best of men. Abdu'l-Baha told her that she should endeavour to give her heart to God, and she said that she would, and then this happened later... and "'Abdu'l-Baha" is the title He chose for Himself. It means literally "Servant of Baha" ("Baha" meaning "glory", refering to Baha'u'llah), but Baha'u'llah called him "The Master", so He is refered to in both ways.
That night the Master had a supper for all who had been with Him at the Mission. It was held in His suite at the Ansonia and He took me and two of the Persians, Valiyu'llah Khan and Ahmad, in His own taxi to the hotel.
As we drove up Broadway, glittering with its electric signs, He spoke of them smiling, apparently much amused. Then He told us that Bahá'u'lláh had loved light. "He could never get enough light. He taught us," the Master said, "to economize in everything else but to use light freely."
"It is marvellous," I said, "to be driving through all this light by the side of the Light of lights."
"This is nothing," the Master answered. "This is only the beginning. We will be together in all the worlds of God. You cannot realize here what that means. You cannot imagine it. You can form no conception here in this elemental world of what it is to be with Me in the Eternal Worlds."
"Oh," I cried, "with such a future before me how could my heart cling to any earthly object?"
The Master turned suddenly to me. "Will you do this thing?" He asked. "Will you take your heart from this other and give it wholly to God?"
"Oh, I will try!"
He laughed heartily at this. "First you say you will and then that you will try!"
"That is because I have learned my own weakness. What can I do with my heart?"
And now the Master spoke gravely. "I am very much pleased with that answer, Juliet."
