I think that it it the diagnose by the pulse. A doctor practising Tibetan medicine checks the pulse by putting three fingers on the same artery as in the conventional method. He presses the certain spots to discern how the internal organs function. Every one of them has its own rhythm which can be learned from the pulse. In such a way, a general condition of the patient, as well as his 12 internal organs, can be diagnosed. It is not an easy technique to master, as one has to learn how to distinguish among 90 types of the pulse. It is also necessary for the doctor to know the natural changes of rhythm of the particular organs, which may vary depending on the patient's age and season of the year.

The main principle of our medicine says that what is enormously important for human health and condition is the energetic balance between three elements: flegm, wind and bile. It doesn't sound convincing for a European. Therefore, I would like to make it clear that the names of these elements should be treated as symbols. Flegm symbolises cold and peace. Small amount of flegm is an evidence of well functioning brain, throat, lungs and bronchial tubes. There is some logic in it - a cool head is widely understood as common sense and symbol of good condition in general. Similarly - cool throat denotes easy and unrestrained breath. Bile, in turn, is hot and dynamic. It governs such organs as liver, stomach, digestive system, which are a kind of chemical laboratories in which heat is indispensable. Finally wind, a changeable element. It happens to be warm or cold. It is worth knowing which is good in what circumstances. Wind is responsible for the lower part of the body.
