“The properties of pedung have also given rise to another belief, with which this paper is more properly concerned,—that of manufacturing pills, to which the god Shourizog, at the supplication of the officiating lamas, imparts the properties of his own divine body, and then imparts to them the curative and protective properties of real pedung. These pills are known as mani-rilbu, or ‘precious pills,’ and are in constant use as medicine among the people of Thibet and Mongolia. Large quantities of them are also sent by each tribute-bearing minion to the Emperor of China. In Chinese, they are called ‘Tsu-mu-yas,’ or ‘thih-ma-yao,’ and must not be confounded with a liliaceous plant of same name (Hanbury’s _Anemarhena asphodeloides_), the rhizome of which is used in medicine, and which is also a product of Thibet. “Perhaps the better name for ‘mani-rilbu’ is ‘tzu-sheng-wan,’ ‘dilated pills,’ which I have heard used for them in Pekin, as will be better seen after reading the following account of the manner in which they are manufactured. “The greater part of the account here given of the process of making the pills is taken from a Thibetan work containing a minute account of the ceremony, together with the prayers to be recited, etc., the title of which is ‘Ceremony of Making Mani Pills’ (Mani Rilbu grub gi choga), in seven leaves. “Verbal explanations from the lamas who explained the text to me are incorporated wherever necessary. “Seven days prior to the commencement of the ceremony the lama who is to conduct it and the priests who are to take part in it commence to abstain from the use of meat, spirits, garlic, tobacco, and other articles of food held impure, or which are bad-smelling, and during the progress of the ceremony, which is twenty-one, forty-nine, or one hundred days in length, none of the above articles are allowed in the temple, nor are unclean persons or those who are partaking of the above prohibited substances.
