The Bathing Sadhana of True Buddha Practitioners
Translated by Janny Chow from the True Buddha News 
(a Semi-monthly publication), #68, published for October 15-31, 1994.

   During his discourse on Tsong-kha-pa's work,
"A Great Exposition on the Stages of the Path of
Tantra," at the True Buddha Tantric Quarter, Grand
Master Sheng-yen Lu transmitted a "Bathing
Sadhana" for True Buddha practitioners.

   In this practice, one first visualizes the 
Principal Deity at one's shrine emit a white light. This
white light rises up and transforms into a 
magnificent and beautiful parasol. One then forms
the following mudra: the left hand forms a fist with
the index finger pointing up; the right hand (with
five fingers extended) is held horizontally, with
the center of the right palm covering the left 
index finger. One chants one hundred eight times
the Great White Parasol Buddha Mother
(Sitatapatre) Armor Mantra, "Hum-ma-ma, Hum-
ni, So-ha." One then visualizes one's house 
(including the bathroom) transform under the 
parasol into an impenetrable armor protecting the
shrine and all the rooms.

   Next, prior to the practitioner's entrance into
the bathroom or shower, one's intent is announced
by snapping the fingers once. Before showering
or bathing, one first performs the Armor 
Protection and chants seven times, "Om, bo-ru, 
lanjeli."

During the shower, one performs the 
following "purification." Visualize the Personal Deity
appearing in the Space above, sitting on a lotus.
From the stem of the lotus, a white light flows
down to shine on one's body. One then joins the
palms to chant the Personal Deity's Heart Mantra
or the Heart Mantra of Padmakumara, "Om, 
guru, Lian-sheng Siddhi Hum." This is chanted seven
or twenty one times. Finally one visualizes black
vapor (one's negative karmic energies) exiting
from one's soles and going down the drain. This
is an excellent method which integrates "sacred
boundary formation," "protection," and 
"purification."
