More than four centuries ago there lived a priest named Gendun Tub who was a disciple of the founder of the New Sect. It was this priest who first originated the practice of invocation of oracles which was subsequently elaborated into a peculiar habit of selecting incarnations. It happened in this way. When Gendun Tub was about to expire, he left word that he would be reborn at such and such a place. Enquiry was made, and the birth of a boy was ascertained to have taken place at the specified place. This would not be particularly marvellous were it not for the fact, as recorded in tradition, that, as soon as he could articulate, the boy declared his wish to return to his temple, the name of which he declared to be Tashi Lhunpo, the very temple where the venerable Gendun Tub had died. There was no longer any doubt in the minds of his faithful disciples and followers that their master had been reborn in that boy. The boy was conveyed to the temple, was there brought up, and was finally installed as the second Grand Lama, called Gendun Gyamtso.
Nothing particular occurred in this matter of incarnations during the periods of his third and fourth successors, but they grew quite popular afterwards, especially in the days of the fifth and the sixth Grand Lamas, till at last the whole system of the consultation of divine oracles assumed the shape in which it is found to-day. The fifth Grand Lama was a great promoter of the oracle system. His name was Ngakwang Gyamtso, and though the head of the New Sect, he investigated the texts and all matters of the Old Sect and introduced into his own sect many things pertaining to the Old. Oracle-invocation was extensively practised in his time, and the privilege of undertaking this solemn work was entrusted to four temples, or rather the deities presiding over them, namely Nechung, Samye, Lamo and Gatong. From the fifth Grand Lama also dates another innovation of far greater importance, that is to say, the establishment of Hierarchical Government.
Before his time, the Grand Lamas held only spiritual power, and had nothing to do with temporal or administrative affairs, for the Grand Lamas had no territories to administer except a small glebe.
About that time a powerful Mongolian chieftain named Shrī Gaumi Tenjin Choe Gyal invaded Tibet and subdued all the petty tribes that had hitherto existed there. These numbered thirteen, each counting according to tradition ten thousand families. Tibet may thus be considered to have contained one hundred and thirty thousand families, and, strange to say, this is also believed to be the present number of the population, according to popular accounts.
The Mongolian conqueror disposed of the districts he had subdued in a very interesting manner, for instead of bringing them under his direct control he presented the whole region to the Grand Lama of the day. Thus originated the system of the Hierarchy, which therefore dates only about three centuries back. But to return to the subject of oracle-consultation.
By this time the process of consultation had to undergo considerable modifications, owing to the fact that the high Lamas who were to be reborn not unfrequently omitted the trouble of enlightening others about the places of their re-appearance on the earth. These places had to be discovered therefore, for the Tibetans firmly held, as they do even to-day, that high Lamas who die are sure to re-incarnate somewhere after the lapse of forty-nine days from the day of death. Hence arose the necessity to determine the place of such re-incarnation, and this task devolved on the oracle-invokers of one of the four particular temples mentioned before.
The process as it is in vogue at present is essentially identical with that prevailing in former times, and is exceedingly strange, to say the least of it. The mediums or invokers who perform this holy business behave themselves in such an extravagant way that the uninitiated would consider them to be stark mad.
The consultation of the oracle is performed by a number of priests, one of whom is a medium, the rest being assistants. These beat drums and strike cymbals, whilst others chant the Texts. The medium is attired in a gorgeous fashion. He wears a big head-cloth with silk pendants of five hues hanging from behind. Sometimes strips of glittering brocade are used instead. The garment is not unlike that worn by Japanese priests, and is of yellow or red satin, decorated with figures of flowers. From the knot of the sash hang long strips of cloth. Thus attired, the medium waits for response from the deities, remaining with closed eyes in a half sitting posture, while all the time the discordant sounds made by the orchestra are kept up. After a while he begins to tremble and shake, this movement gathering force, till all of sudden he either falls on his back or jumps up, according to the nature of the deity who responds to the invocation, and has now descended into the body of the medium. He will then say, still continuing to shudder, that the particular Lama has re-appeared at such and such a place, and in such and such a house which faces in a certain direction; that the family consists of a certain number of members; that a baby born on a certain day is a re-incarnation of the dead Lama, and so on. An enquiry is then made according to the direction and of course the pronouncement of the oracle is confirmed, and a baby corresponding to the description given is found in the house. The boy is left under the care of his mother till he can be weaned, and then he is brought to the specified temple where he is educated. In education special care is taken to inspire in him the strong self-confidence that he is a holy re-incarnation.
At any rate the practice of invoking divine oracles extensively came into vogue from the time of the fifth Grand Lama, and is used for all matters great or small, from vexed international problems to trifling questions that easily admit of solution.
The oracle-giving deities, as I mentioned before, are four, and they are regarded as the guardian angels of the Lama Hierarchy. Of the four Nechung is the most powerful.
