Can anyone tell me about the Deity Jnana Sagara in Tibetan Buddhism?
I know Jnana means actualized wisdom and related to the Vipassana nanas per wiki search. Sagara was a Vedic King. I don't know if this will help your search. I remember seeing this name but I can't remember where.
Jñāna: knowledge, a mode of prajna, characterized by decisive (niscita) understanding; also characterized as knowledge
that repeatedly discerns; knowledge realizes and comprehends, fully and thoroughly. http://abhidharmakosa.files.wordpress.c ... -7-web.pdf
