                    HpS - Very nice....    Please keep the links and we will talk with you as our work progresses.  Now we are jumping right in and explaining our Bhakti-vaibhava work to Dr. Jung.  So far it is working well, but of course, it requires that we go back from the "mythical thinking" and get back to the Sankhya in the earlier cantos to make a more firm ground for it, but is nice to taste the higher thing first.
