The present fasciculus of the «Bibliotheca Buddhica» contains
the edition of the original text of the Prajñā-pāramitā-ratna-guṇa-saṃcaya-gāthā or simply Saṃcaya and of its Tibetan
translation. It has been prepared on the foundation of a Chinese
xylograph which has been discovered by Prof. M. Tubiansky in
Mongolia, in the monastery of Mañjuśrī (Mandzuśriin kiit) among
other valuable texts, the most important of which is Nāgārjuna’s
Catuḥstava in the original, to be edited by Prof. Tubiansky himself...
