from the rgyud bzhiâ, the 4th Medicine Tantra
translated by Tsering Dolma
This is from the chapter
about pulse diagnosis. Pulse and the cosmo physical energies.Briefly,
the cosmo-physical energeticle influences of the pulses are revealed
through the solar, lunar and seasonal relationships. Before we examine
these influences it is first necessary to understand the relationship
between these energies themselves. This is revealed by the mother
- son - friend - foe cycles. Solar and Lunar influences. Within
the human body there are three main subtle channels with positive,
negative and neutral energies. These channels are known resepectivly
as khang-ma, ro-ma and dbu-ma. The khang-ma channel is influenced
by the moon (earth and water cosmo - physical energies). The ro-ma
by the sun (fire [and wind] cosmo-physical energies). The dbu-ma
by Rahu (spatial cosmo-physical energies). During nightfall the
lunar influence is stronger, the pulse energies are slower and cooler
than normal. On the other hand the solar energies are strong during
the day, and are warmer and beat more rapidly. It is for this reason
that the correct time to take the pulse is when these two energies
are in a dynamic state of equilibrium. This occurs just at the break
of dawn when the lines on oneâs palm are clearly visable.
(This also represents the start of the Tibetan day, which changes
in clcck time every day.
The Tibetan sphygmic calender has 360 days. These are divided into
20 parts consting of 18 days each. The first 72 days are spring
when the wood energy is dominant and exerts a strong influence on
the liver/gall bladder pulses. This period is then followed by the
18 days Îin betweenâ season, when the earth energies
are much more dominant and excert a strong influence on the spleen/stomach
pulse (for the influence of other seasons refer to sphygmology p.
85). Its imperative for the physician to know the exact season whilst
checking the pulse or else the diagnosis may prove to be wrong.
For instance, if the physician is not aware that s/he is checking
the pulse during the spring, then the stronger liver/gall bladder
pulsations will be diagnosed as an ailment. It is precisely for
this reason that the Îrgyud bzhiâ elaborately explains
how a physician can identify the reasons through the observations
of the stars, birds, trees, etc.
