Constance Wachtmeister

According to Readers Guide to The Mahatma Letters to A. P. Sinnett:

Wachtmeister, Countess Constance, companion of HPB and co-worker after HPB's return to Europe in 1885. Shortly after HPB's death, the Countess wrote a small book entitled Reminiscences of H. P. Blavatsky and "The Secret Doctrine" in which she told of her life with HPB from 1885 until the latter's death. ML index; HPB VI: 448; D, p. 562 et seq.

In the autumn of 1885 the Countess was getting ready to go to Italy to spend the winter with some friends, when a singular phenomenon happened:

I was making preparations to leave my home in Sweden to spend the winter with some friends in Italy. . . . I was arranging and laying aside the articles I intended to take with me to Italy when I heard a voice saying, "Take that book, it will be useful to you on your journey." I may as well say at once that I have the faculties of clairvoyance and clairaudience rather strongly developed. I turned my eyes on a manuscript volume I had placed among the heap of things to be locked away until my return. Certainly it seemed a singular inappropriate vade mecum for a holiday, being a collection of notes on the Tarot and passages in the Kabbalah that had been compiled for me by a friend. However, I decided to take it with me, and laid the book in the bottom of one of my traveling trunks.

On her way to Italy she stopped at Elberfeld and satyed for some days with Madame Gebhard. When she was about to depart she got a telegram from H. P. Blavatsky requesting the Countess to join her at Wurzburg. Soon after she arrived, she had the following incident:

I remember very well that it was then, on going into the dining room together to take some tea, that she said to me abruptly, as of something that had been dwelling on her mind.

"Master says you have a book for me of which I am much in need."
"No, indeed," I replied, "I have no books with me."
"Think again," she said, "Master says you were told in Sweden to bring a book on the Tarot and the Kabbalah".

Then I recollected the circumstances that I have related before. From the time I had placed the volume in the bottom of my box it had been out of my sight and out of my mind. Now, when I hurried to the bedroom, unlocked the trunk, and dived to the bottom, I found it in the same corner I had left it when packing in Sweden, undisturbed from that moment to this.
