The Dharani of Great Pity—Mahakarunikacitta Dharani in Sanskrit,
dharani meaning entire control—comprises the holy names of the
Buddhas and bodhisattvas. Beyond expounding, a dharani is left wholly
to chanting as sounded, with the faculty of mind in concentration, unto
entrance in samadhi where dual application of mind ceases, and in
attainment of profound samadhi. Such is retaining the dharani.
The Dharani of Great Pity is read in Sanskrit—a slightly overtaxing job to
begin with, perhaps. Seek guidance from fellow practitioners; find a
printed version with phonetic instructions, even CDs for teaching.
Familiarize with pronunciations by learning one or two lines per day
through a couple of months and, further, succeed in reciting by rote.
