From FPMT International Office:
Our hearts and prayers go out to the victims of the tragedy that occurred on the evening of Sunday, October 1, 2017, in Las Vegas.
Lama Zopa Rinpoche always advises to make strong prayers to Medicine Buddha for anyone who is dying, sick, injured, or who has already died from violence such as that which occurred in Las Vegas or elsewhere.
Please make prayers for the sick and injured to recover. For those who lost their lives in the tragedy, please make prayers for their families and survivors to be blessed by and receive healing from Medicine Buddha. Also, please make prayers for those who have died to be born in a pure land and become enlightened, or to receive a perfect human body, meet with the precious Dharma, receive teachings and to achieve enlightenment as quickly as possible.
Medicine Buddha practice can be done for anyone who is sick, dying, or even who has already died. Reciting the mantra of Medicine Buddha is one of the best practices we can do at this time.
The mantra of Medicine Buddha is:
TADYATHĀ / OṂ BHAIṢHAJYE BHAIṢHAJYE / MAHĀBHAIṢHAJYE [BHAIṢHAJYE] /
RĀJA SAMUDGATE SVĀHĀ
