How would you explain ‘personal nature’ in the context?
Four of Sra. Frida’s paintings will be included in an exhibition at the National University. Likely she is happy about it, though she has not mentioned this, or anything else of a personal nature, since the last inspection of this journal. She comes to the house almost daily to see Lev, but avoids the staff.

How would you explain ‘personal nature’ in the sentence: …or anything else of a personal nature…?
Thanks!
PS: It’s from the Lacuna by Barbara Kingsolver.

Answer

A comment of  'a personal nature' in this context means mentioning her personal feelings.

She hasn't said whether she's happy about the inclusion of her paintings in the exhibition, and nor has she said anything else 'personal' on the topic. She's maybe mentioned the facts, but not her feelings.

Answer

thank you!

Answer

Something "of a personal nature' means something 'private'. 
In this context the word 'nature' is not about the physical world, it is about the personality of a person (can also be used for animals).
