The Buddha told Manjushri, "Passing from here to the east, beyond
Buddhalands numerous as the sand grains in ten Ganges Rivers, is a
world called 'Pure Vaidurya.' The Buddha there is named Medicine
Master Vaidurya Light Tathagata; One Worthy of Offerings; Of Proper
and Equal Enlightenment; Perfect in Clarity and Practice; Well Gone
One; One Who Understands the World; Unsurpassed Lord; Taming and
Regulating Hero; Teacher of Gods and People; Buddha; Bhagavan.
Manjushri, when that Buddha, World Honored One, Medicine Master
Vaidurya Light Tathagata, was practicing the Bodhisattva way, he made
twelve great vows that enable all living beings to obtain what they
seek.
"The sixth great vow:
'I vow that in the future when I attain Bodhi, to cause sentient
beings whose bodies are inferior and whose faculties are imperfect,
who are ugly, dull, blind, deaf, dumb, mute, paralyzed, crippled,
hunchbacked, leprous, insane, or have various other kinds of
sicknesses and sufferings, to become upright and intelligent upon
hearing my name. May they all possess perfect faculties and be free
of sickness and suffering.'
"The seventh great vow:
'I vow that in the future when I attain Bodhi, to cause sentient
beings who are oppressed by many illnesses and who are without aid,
without a place to turn, without a doctor, without medicine, without
relatives, and without a family, who are poverty stricken and filled
with suffering to be cured of all the various sicknesses upon having
my name pass by their ear, so they are peaceful and happy in body and
mind. They will have a family and relatives, also acquire an
abundance of property and wealth, even to the point of certifying to
unsurpassed Bodhi.'
"Moreover, Manjushri, when Medicine Master Vaidurya Light Tathagata
attained perfect enlightenment, by the power of his past vows he
contemplated all the sentient beings who were suffering from the many
kinds of diseases, such as emaciation, paralysis, tuberculosis,
biliousness, or fevers. Some were afflicted by voodoo or by poisonous
spells. Some died naturally when young, while others experienced a
violent death. At that time, wishing to put an end to all these
various sicknesses and sufferings, and to supply whatever those
beings sought after, the World Honored One entered a samadhi
called "extinguishing the suffering and distress of all living
beings." After he entered this samadhi, a great light came forth from
his flesh-cowl. From amid that light this magnificent dharani rang
forth:
"Namo bhagavate bhaishajya-guru-vaidurya-prabha-rajaya, tathagataya
arhate samyak-sambuddhaya tadyatha Om, bhaishajye bhaishajye-
bhaishajya-samudgate svaha."
"Then, at the end of the mantra that came forth from the light, the
earth trembled and emitted great light. All living beings' sicknesses
and sufferings were cast off, and they felt peaceful and happy.
