Noted. I supposed by chanting amituofo I am
accumulating merits for myself.
Do you know anything about the pills from tibetan buddhism?
I was given by the shifu but wonder if there is any
expiry date. I don't not eat any more after so
long.
With regards to the pills, I assume you could be referring to
Mani Pills.
Another forummer Weychin gave me this information in the
past.
About the
Precious Mani Pills These pills have been prepared
according to the proper Vajrayana ritual and method laid down in
the Karma Kagyud Lineage. Under the guidance of the most Venerable
Shangpa Rinpoche and Venerable Dupsing Rinpoche, the monks from
Jangchub Choeling Monastery and their devotees have meditated and
recited the Avalokiteshvara's Mantra (OM MANI PADME HUNG) over one
hundred million times to bless the Pills.
The sacred substances that were used in the production of the
Pills are:

Some of the
Benefits
According to Guru Rinpoche (Padmasambhava), whoever consumes the
properly prepared "Mani" pills will be blessed both physically and
spiritually. These pills can purify one's negative karmic forces
and turn the mind towards the Dharma. They can prevent epidemic
disease, poison, etc. and remove obstacles such as curses and black
magic. A dying person will be liberated if he takes it.
The pills can be consumed by themselves or dissolved in water
for drinking. Alternatively, one can also inhale the fumes from
burning the pounded pills. After taking the pills one should recite
the Six-Syllable Mantra (OM MANI PADME HUNG) several times for the
pills to be more effective.
