In his excellent and highly readable new biography of Jamgön Kongtrul Lodrö Thaye (‘jam mgon kong sprul blo gros mtha’ yas, 1813–1899), Alexander Gardner states (p.275) that Kongtrul never met Dza Patrul Rinpoche (rdza dpal sprul, 1808–1887). For this, he relies on the following statement from Joshua Schapiro’s thesis:
“There is, to my knowledge, however, no evidence in the biographical archive that Patrul had a relationship with Kongtrul […]. Kongtrul does not appear in Patrul’s biographies, nor does Patrul appear in Kongtrul’s autobiography.” (2012: 51)
It is indeed true that the principal biographies of these two great luminaries of nineteenth-century Kham make no mention of any direct contact or relationship. But this is not to say that the two never met at all.
