The longevity ritual is known as tshedrup (or bla ma tshe dpag
med kyi sdrup pa in full). The question ultimately is about
validity and efficacy of tshe drup or tshewang because restoring
bla and life force is part of it. The longevity rite originated
with Guru and Madarava who practiced it in the Maratika cave, and
was practiced later by disciples of Guru. Singye Dzong and
Takstshang were important sites where Yeshey Tshogyal and other
disciples practiced and witnessed the mandala of Guru Amitayus
Yab-Yum. The central diety for visualization was Guru Amitayus,
also known as Guru Pema Thodthrengtsal, and his consort (blama tshe
dpag med yab yum). The origin and transmission of the tersar text
of longevity practice ‘chimed rsog thig’ (Immortal Life’s Creative
Seed) is a subject of illuminating joint article by Cathy Cantwell
and Robert Mayer (Cantwell G and Mayer Robert, 2009).
The terma hidden by Yeshey Tshogyal was revealed in 1908 at the
cave of Singye Dzong by Zilnon Namkhai Dorji (1874-), the root lama
of the late Dudjom Rinpoche (1904-87) and Karmapa Khachap Dorji.
The deduction of terma text of ‘chimed srog thig from dakini script
was carried out most likely when Zilnon lived in Bumthang with the
patronage of King Ugyen Wangchuck, because its colophon mentions
the palace and king of Lhomon. The terma titled ‘chimed rsog thig
corpus was incorporated by Dudjom Rinpoche in his gsung ‘bum dam
chos rin chen nor bu’i mzodm, Vol pha :193-554. ‘Chimed rsog thig
corpus suggests that longevity is affected not only by theft and
attack on life force by various powerful spirits such as driza,
shinje, luwang, nodjin, firegod, cannibal, wind god, and four kinds
of demons.
There are other credible factors: (1) the decline of life force
and breath, (2) the loss of body and mood, (3) the interruption in
the subtle neurological, respiratory and libido processes
(rtsa-rlung-thigle) (Dudjom 1999: pp. 110-122). Accordingly, a
comphrehensive method of recovering longevity encompasses five
elements: (1) ritual seeking jinlab from the assembly of Amitayus
Buddhas and protector deities: (2) burnt offerings to the fire gods
of wisdom (yeshey kyi me lha); (3) casting away of effigies of
scapegoat as substitutes for meat, blood and life force to
repurchase bla and life force (sha rin khrag tsab srog gi glud, see
Dudjom 1999: 354); (4) consumption of herbal pharma products and
other essences such as that of minerals (Dudjom 1999: 449-450); (5)
the ultra secret practice of union following sbyor dnyos rje gsum
(Dudjom 1999: 492-506); (6) longevity blessing (tse dbang), and (7)
psycho-physical yogic exercise to work on subtle parts of
neurological, respiratory and libido systems; and, more
importantly, (8) visualisation and meditation that activates
perceptional mechanism in a different way and reorients
consciousness (see Part 1 of this article). In the case of
longevity blessings with longevity nectar (‘chimed rdud tsi),
longevity arrow-silk (tse dhar) and longevity pill (tse ril), the
recipient visualizes Amitayus blessing the recipient with healing
power and energy through the performing lama. One of the key
assumptions behind the longevity practice is the body as an open
system influenced by the environment (psychological, sociological,
nutritional, spiritual etc.) in the widest sense of the term. If
the body is an open system, then a mix of naturalist and
personalist approaches to health is more comprehensive.
