from a series of tweets by Jetsunma Ahkon Lhamo:
If you see any animal dying, even a bug or worm, recite audibly *OM AMI DEWA HRI* then *OM MANI PEDME HUNG* to bless them, for a good rebirth.
If you or someone you know suffers from mental confusion recite *OM AH RA PA TSA NA DHI* to Bodhisattva Manjushri and then *DHI D D D….. At least one full MALA of each.
If you are on the spiritual path and wish to find your Guru or repair any connection with GURU recite *OM AH HUNG BENZAR GURU PEMA SIDDHI HUNG* That is the Mantra for GURU Padmasambhava, the lotus born Guru.
If one sees a disaster, natural or otherwise; or many suffering pray to Tara, Mother of all Buddhas recite; *OM TARE TU TARE TURE SOHA*
