Four Initiation Cards (Tsaklis) of Padmasambhava
Four Tsaklis (Buddhist miniature paintings).
According to scholar Stéphane Arguillère, “It is unlikely that these are from Mongolia as this is 100% Nyingmapa material–a branch of Tibetan Buddhism which I think did not spread to Mongolia. These must be parts of a larger series that must include aspects of Padmasambhava corresponding to each group of verses ending “bsam pa lhun gyis brub par sbyin gyis rlobs”, “bless [me] so that [all my] wishes are spontaneously accomplished”.
The verses on the back are parts of a very well-known prayer called bSam pa lhun grub ma, “The Spontaneous Accomplishment of [all] Wishes”. But there are no further clues about which sub-branch of the Nyingma school (or maybe Kagyüpas praticing Nyingma traditions) it comes from.
