Dear Sri Dwivedi,
The Yog
ācārabhūmi is a huge text, much of which has not yet been recovered in its original Sanskrit. As may be seen in its Chinese and Tibetan translations, it consists of five major parts. The Vini
ścayasa
ṃgraha
ṇī is the second of these five major parts. Only small fragments of the Vini
ścayasa
ṃgraha
ṇī in the original Sanskrit have so far been recovered. Virtually none of parts three, four, and five of the Yog
ācārabhūmi in the original Sanskrit have been recovered. However, we are more fortunate with the first and primary part of the Yog
ācārabhūmi, the so-called maul
ī-
bhūmi. This consists of seventeen sections or
bhūmis. Almost the whole of this was discovered by R
āhula S
āṅk
ṛty
āyana on his trips to Tibet in search of Sanskrit manuscripts in the 1930s.
Sections or
bhūmis one through five were edited by Vidhushekhara Bhattacharya and published in 1957 as
The Yogācārabhūmi of Ācārya Asaṅga, Part 1, University of Calcutta. I have posted a scan of this here: http://www.downloads.prajnaquest.fr/BookofDzyan/Sanskrit%20Buddhist%20Texts/yogacarabhumi_chapters_1-5_1957.pdf
Most of the other sections or bhūmis have been published individually in various publications, which would take too much space to list here. Two of these
bhūmis, however, circulated as separate texts in old India: the
śr
āvaka-
bhūmi (section thirteen), and the bodhisattva-
bhūmi (section fifteen).
mi was first published in 1973 by the K. P. Jayaswal Research Institute, Patna, edited by Karunesha Shukla, as
. This is probably available online somewhere. Part II of this was published 1991, containing introduction, appendices and indices. A new and improved edition of the
mi Study Group of Taisho University in Tokyo is being published in Japan in parts since 1981.
