56-NO TO GEMOLOGY
It is quite clear from following episode
Ruano Bogislav, Disciple, had something on her mind. She asked, "Is it true that certain substances hold impressions?" Being a rather strange question, Baba shrugged His shoulders, and Ruano continued, "When you called me to come to India in 1936, I had little money. But with a friend, I happened to go to a fortune teller, who said I should take off the old Chinese bracelet I was wearing, and things would improve. She said it had belonged to someone who had lost everything in life. So I did. I thought, why not? And, almost at once, someone sent me a cheque for five hundred dollars, enough for the boat to India."
Baba spelled on the alphabet board (which Mani read), "It is true, certain substances or creatures at the four corners (turns) of evolution hold impressions – certain metals, gems, black wool, cats, dogs. Not much should be said about it because it creates superstition." (Lord Meher, 1st. ed., Bhau Kalchuri, Vol. 11, p. 3878)
