Aušra Augustinavičiūtė rightfully notes that she gave up given her own failure to understand such an esoteric perspective.
She said nothing of the sort. Perhaps she did fail to understand what Jung intended but this is not how she viewed it. Jung was merely a stepping stone for her.

It should also be noted that Augusta was no stranger to the esoteric sciences (nor am I, for that matter). By all accounts she delved into them deeply in her later years. But everything has its place in the search for knowledge.
