From Lama Tharchin Rinpoche a piercing and meaningful teaching in the form of a story.
There once was a lama who met a man with whom he had a good karmic connection. The lama knew this person could attain realization but he was a high government official and the lama, being a lowly person, didn’t know how to make a connection with him.
As fortune would have it, the official was carrying a sweet puppy dog. So the lama said to him, I really love your puppy dog! Please give it to me! All my life, I've never never had a desire as strong as this one. I really want your puppy!
The official immediately refused the lama's request but the lama persisted. Finally, the official conceded to give the puppy to the lama on the condition that the lama solemnly promise never to give the puppy to someone else. The lama agreed to this condition and took the puppy home.
The very next day, the lama gave away the puppy at the first opportunity! When the official discovered this, her was greatly angered and told the lama, in no uncertain terms, that he would never again trust him since he had broken a promise made in the presence of the Three Jewels.
The lama replied, I’m so happy you've realize that you can't trust me! You’re not real. Your puppy is not real, I'm not real. The Three Jewels are not real. This is the only thing I can teach you. Nothing in the world is real.
Then the lama proceeded to teach the official about ultimate truth and the true nature of mind, emphasizing that the nature of mind is trustworthy.
The official contemplated this for sometime. Eventually he resigned, became a practitioner and attained realization.
