Dear list members,
I've been told a text called prapañcasārasaṁgraha contains several dhyana shlokas to Dhanvantari. But I'm not clear what text is meant by prapañcasārasaṁgraha.  I see references to this text on the internet.  
But on archive.org I only see:
a) prapañcasāratantra attributed to Śaṅkarācārya
b) prapañcasārasārasaṁgraha by Gīrvāṇendra ṣarasvati

Any ideas would be appreciated.
Thanks,
Harry Spier
