I can never be too thankful for the enormous amount of care and trouble he took in my psychic education. Patiently and over and over again he would make a vivid thought-form, and say to me: "What do you see?". And when I described it to the best of my ability, would come over and over the comment: " No, no, you are not seeing true, you are not seeing all; dig deeper into yourself, use your mental vision as well as your astral; press just a little further, a little higher." This process often had to many times repeated before my mentor was satisfied. The pupil has to be tested in all sorts of ways and under all conceivable conditions...."
